Peabody Creedmoor Martini mistake. What to do?

Peabody Creedmoor Martini mistake.... What should I do?

So I bought, for a long price, a nice Peabody Creedmore. It has a heavy weight round barrel, in of all things .38-55.  Sorry, all my pictures are too big to post here.

I believe the barrel to be a replacement, since all the Creedmores I have seen are half octagon. 

So, do I leave it as is, rebore it to some .44 or .45 caliber, or get a half octagon barrel made? 

Does anyone know someone who's competent to make a half octagon correct replacement barrel? I have a correct Creedmore to copy from.

Thank you!

Ballards may be weaker,

A correct Creedmoor barrel would be easy to make for any competent machinist or gunsmith. Simply begin with a full octagon and turn down the front 2/3rds or whatever is desired to round.
I've got a couple original Long-Range rifles that were nicely rebarreled with correct .44 and .45 barrels in 34" length and half octagon to match the original barrels.
Contact a gunsmith and tell him the chambering you want, and dimensions of the octagon and round parts and have one whipped out. Just make sure he's a REAL gunsmith, or competent amateur.

I have access to the pictures of this gun.  They are to large to post direct her.  I am wait permission from OP to resize and post them.

An interesting marking on this gun is this one. Anyone recognize it?

In all my years of single shots I've only had one Peabody Martini. It was in 50-70 and I wish I still had it.

Are the initials J. H. G.?  1947 time period is right.  Is this the James Grant who wrote the Single Shot Rifles series of books?  If so, with that provenance, and just my opinion, is that it is worth a bunch more as a 38/55 than trying to reset the clock to one of those old Peabody cartridges.

First gift my then-new wife ever gave me was a signed copy of Single Shot Rifles.

Thank you all!  DoubleD will resize and post the pictures here. 

Alas James J. Grant was the single shot author.  The signature is actually J H D ,  with the D turned 90 degrees. Oops? Or an intentional quirk?

But we are all such pack rats, if the original barrel was good and just changed for caliber, it may well still exist in a shop somewhere! 



The work is so good I imagine there must have been plenty of other work that JHD signed.  I wonder if anyone might know who he was?  The rifle came to me from Indiana.

You have a real problem. The Peabody Martinis had Henry-style rifling, and I don't know who can cut that style. The Creedmoor Long Range was chambered in the .44-100 Peabody; another hard one to come up with.

Was the .44/100 Peabody a bottlenecked cartridge?  Somewhere I have an original.  I paid $5 for it back in the 1950s.

Yes, bottle necked. As best I can tell, basically the Turkish cartridge with a longer neck.

Note the screw slot positions on this action match the screw slot positions of one of the rifles in one of Grants.  It may be just the way the builder timed his screws or maybe the same action.

I am going to do another post with additional pictures as I don't know it there is picture quantity restriction in this soft ware.

I am not very knowledgeable on these guns, but the butt stock appears too a be replacement-should it not have a panel against the action?

Maybe the next time you pay the long dollar, you might get Jim Grant's books on single-shot rifles. There are five volumes, the first three being the best. They are out of print, but you might find them on the forum or on ABE books. You are into a rifle that has replacement sights (and if you can find a set, you will pay!), a replaced barrel, and to try to find an original, or to have a replacement made, will cost a lot. Then to find dies to make the original cartridges will be a challenge. I write books, and I think you need to buy some before you get too much far along. Tom Rowe

Amen to this.  Whoever JHD was, he turned a rifle that is difficult to supply with brass and one with considerable recoil into one that is usable, has easy-to-find brass, lots of cast bullet choices, and has lots of current loading info.  Back in 1947, he did you a huge favor.   

Now we need to know who JHD was.

The shame is that he took a relatively rare rifle, with fewer than 200 probably made initially, in really nice condition, and turned it into a parts gun with limited value.

Ouch! 😫

Unfortunately it’s true!  Probably wasn’t worth a lot back in ‘47….

Perhaps Mr. Rowe feels that all-original Peabody Creedmoor models are too rare or too shoulder-punishing to be shot regularly today.  But you also must admit that way back then gunsmith JHD turned the OP's Peabody into a very shootable rifle and did so with a lot of class.  And Value, like Beauty, is often in the eye of the beholder.
