Thanks, everyone for your comments.
Drew, I looked into Littlegun and they have a site , where they will do homework, charge about $7 for six months subscription, and research your gun. I tried to set it up, and it wouldn't take my credit or debit card info...so ??? I followed up with the people that host the site, but couldn't make progress. Had several conversations with Alain Trigger, but to no avail. Anyone ever had luck with the littlegun 6 month subscription process?
Also, Pete, there is a lower case "t" just under the barrel weight markings on the flats, in the last pic on my post, and that's what I thought was date code....corresponding to 1941. I'm really more interested in trying to establish a fair market value for the gun, than learning much more about the company.
There just doesn't seem to be many out there to compare to.
There is one on gunbroker now with a start of over $5000, has Abercrombie and Fitch stamped on it, but is a similar style F. Dumoulin boxlock.it has an English straight stock, but frame is very similar...no bids however.
any more info or opinions out there?...much appreciated!
