While wandering through gun shops looking into what scope and mount combo to use on a 310 Australian martini based 221 fireball I came across an externally adjustable scope mounted on a 310. The scope has no markings on it I can see but looks like a Weaver. Did Weaver ever make an externally adjustable scope? I don't have access to Strobels book on scopes so a reference to it will not be helpfull.

Many thanks for any info!

Yes, I have a 2-8 power weaver (V8) with the external adjustments on a Stevens Ideal in 22LR.  There was some discussion here awhile back about them.  There were also some comments about their lack of suitability for high recoiling rifles.  22-250 should be fine though.  There are usually some for sale on eBay and GUNBROKER.com.  Terry

There were several manufacturing this typ of scopes. Pictures would be helpful. Does it have any markings on it at all? I have one marked onl 8X that is a Winchester made for the 75 .22 target rifle. Some of the Stevens were not marked as far as I know. Post some pictrues and somone here should be able to identify it.

Attached is a picture of the Weaver V8.  There is no turrent adjustments and all the windage and elevation adjustment is in the rear mount.  The scope is a solid tube, much like the B&L Balvar scope.  I believe many are used with the Balvar mount as it is stronger.  The one I have has very nice optics but the scope's zero is reliant on the strength of the rear springs.  Terry

Here is another picture of the Weaver V8 mounted on my Stevens Ideal.  Terry

Thanks for the pictures Terry! Those are the first I've ever seen!

They show up on eBay quite regularly.  I got mine a couple years ago on eBay for about $50.  It's was in excellent condition although it was missing the adjustment caps.  The prices for the V8, as well as the rest of the vintage Weaver line, seem to have doubled in the past couple of years.  Other's opinions may differ, but I don't think they worked out very well as a hunting scope since the rear of the scope was basically floating, and the zero adjustment was maintained by the tension of the adjustment spring in the rear mount, not unlike the rear mounts on a Fecker or Unertl.  It doesn't take much of a bump to move the zero slightly under hunting conditions,.  It seems to be a very rugged scope though and I understand work well in the B&L Balvar mount.  I think there are currently three for sale on eBay.  Terry

Actually I ran into the other variation of mount at a weekend gun show. This one has a spring affair between rings and the front base has one plane of adjustment and the rear base has the second plane. Have no idea what was first or second generation.
