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,
but they sure are neater!

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.
