Square to octogon barrel gun

[David R. Pennington]

I have a plan for a rifle drawn by Curt Hemlepp in 1976 that was based on a rifle in George C. Neumann's collection that had a square to octagon barrel. Anyone know anything about this piece? Sounds interesting. Would like to see pictures of it.

  This rifle is pictured in at least one of George Neumann's books. Track of the Wolf sold a modern copy of it a few years ago, and it was available in their on-line archive. The pictures are of very high quality.

Over the years I know we made two of these strange barrels, one was built by Dave Dodds, but have no idea of where
it might be.   Lot of fun to make, takes a big piece of steel to do a square barrel........Don

Dave, I have a copy of that plan also and can"t tell you much about the provenance of the firearm but it was on display at Valley forge when I visited there in 2008.  I looked at it in the case and all I remember is thinking the lock looked  or reminded me of a dutch musket lock.  
FWIW curator told me they have all or most all of the Neumann collection and I was researching fabric used in original cartridge box shoulder straps. got to handle a few of those. Word was they were looking for funding and had plans to build a larger building to display more of George's stuff.
