Well it's a great gun none-the-less but a bit of air has been let from my baloon that we can't positively ID it. If photos might be useful, anyone interested in continuing to solve the mystery may send me their private address and I'd be grateful for the help. Send to yojo18840 at my Yahoo account. There are already photos on Hill Rod and Gun's web site, in Charlie's 'Archive' section of previously sold guns, but I can send close ups of the flats or the engraved maker name...
