Vintage 4X Tasco Brass Scope

Print Post  
So I bought this last weekend at an auction and waiting for it to arrive - hoping it works and I can mount it on my 1871 Buffalo Classic 45-70.


The catalog description was as follows.



BRASS SCOPE, CLEAR VISIBILITY WITH FINE CROSS HAIR RETICLES. MARKED 4X15 JAPAN, A-521. COMES WITH BRASS SCOPE RINGS. 17 3/4" OVERALL


I'm also attaching a few pictures. If anyone can tell me more about this scope it would be appreciated.


Regards, Retreever

First one of those I've seen with that type mounts, looks like a lot better mount than the typical ones on import brass scopes from Tasco and others. I am guessing that recoil from a 45/70 may be more than that type of scope is made for unless there is some provision for the scope to slide in the front mount which is not apparent in the photo. Hopefully somebody has used one on a rifle with heavy recoil and can share the experience.

I was at a gun show once with a friend and he had spent all his money, we stumble on one of these (he saw it first), I bought it for him (he paid me back shortly of course - most only have a couple hour window for things like that  Wink ) Wished I have kept it...
I remember the scope being of fairly good quality and the mounts being far better than the Navy Arms I eventually found to fill my want void...  He ran his on a 444 marlin Rolling Block and it did well there, I remember him having some issues with recoil and the cross hairs breaking but he was able to replace them with a little creativity.  My NA is on a #3 Ballard and it does well there.

I have one just like it on a low wall .22lr.  Yours has the Unertl style rear mount like mine does it has no click adjustments.  The front mount was made to tighten to the tube but I did not like that I ground the inside so I had two contact points on the bottom of the ring and then put a spring loaded plunger on top like a Unertl.  For mine I had to make a stop ring in front of the front mount to reposition scope and orient it so cross hairs were stright up and down.  Scope is clear but glass is not coated on mine so brightness depends on conditions.  Not a lot of adjustment available so cannot go from 25 yds to 200 yds. On the way to the Doc appt.  if you have questions let me know.

Dennis you were answering as I was.  Thinking my friend used tungsten wire for the cross hairs and mounted a spring like a Unertl some how but I don't recall how he kept it clocked as I don't recall provisions for a key...

I still have one of these, which I bought back in the mid-1960s when I believe they first came out.  And for whatever reason I associate them with either Navy Arms or Numrich and remember them being called the "1903 Scope".  In any case, the first generation mounts were much simpler and only finished where they had to be, and so I always intended to get nicer looking ones to actually use.  Never happened and now likely never will.  Still, TASCO was thought of back then as making good low-cost scopes, and I still wouldn't have any qualms about mounting one of these on a rimfire or low-power centerfire rifle.

The 1903 must reference the mount design as the more common primitive mounts the scope is marked 1860. I have a long Stevens scope from that +/- 1903 era and it is made to slip in the front mount. The mount has a small leaf spring on the under side to provide a consistent return upwards and a small screw or stud that centers in a vee notch to return it to position axially and radially when you pull the scope back by hand after each shot. Simpler to implement than the rib which was the next evolution I presume.

I have two of the 30" long that I got in the 70s', the original mounts looked like brass pluming parts, replaced with mounts like yours. One is on a 50 caliber 40# muzzle loading bench rifle, the other is on a Shiloh 45-70 with a two step rear base to get the adjustment I needed for the longer ranges. Both have slideing mounts and work fine, just have to watch out for the short eye releaf.

Ballards may be weaker,
but they sure are neater!

I remember when those were first offered for sale in both the 17.5" and 30" lengths. I saw them with the big clunky mounts that set the scope off to one side, and had crude adjustments. Never saw any with the mounts shown above?
I have two of the longer versions and replaced mounts on both with higher quality mounts. One is in an old pair of Winchester A5 mounts, and the other in Malcolm style long range mounts. Both of mine have been rebuilt and crosshairs and lenses replaced to better quality. I like them, and they have a very clear view now with the upgrades. One is also more power than the other, so I'm guessing when the lenses were replaced it got higher power lenses?
I darkened both of mine with Birchwood Casey's Brass Black as i hated the shiny brass finish. Much improved their appearance.

Hi Charlie, I don't supposed I could get some pics of your scope mounted?

Thanks Retreever

Mike, can you explain 'sliding mounts' I just got my gun a couple of months ago before then it had been 30 years since I fired a rifle and never ever used a scope.

Thanks, Retreever

A sliding mount requires the front of the scope to be surrounding the tube, but not clamping it tight enough to restrict it from sliding inside the front mount. Normally a leaf spring, or plunger and spring combo keep slight pressure against the tube.
It also requires either a rail on the tube to keep the crosshairs vertical, or a notch in the edge of the mount and a pin or screw in the tube to fit into the notch and index it vertically.

To continue, the point of the sliding mount is that on the recoil of the rifle the scope is free to slide (actually to stay more or less where it started relative to the shooter's eye) instead of giving the shooter a whack in the face. You'll quickly get the idea when you touch off a heavy 45-70 bullet in that light rifle. If the scope is locked into its mounts it will be headed your way fast.

Here is a couple of pictures.  Not sure what you want.  I used standard bases because the barrel was already drilled and tapped.  Had to shim one side to make them wide enough to clamp to and grind clearance for clamp screw.

Thanks Charlie, those are exactly what I was looking for, the scope looks really good on that gun.
