So much obliged.
Obviously you have more mileage than me in these things

. I have visited that first web site, but wasn't patient enough to roll down the page, so i didn't see the specimen you are now showing ... a style indeed similar to mine.That's quite comforting. I meant valueless in the sense of collecting, due to its simpleness and rusticity, looking like an undetermined home made thing. But that was before seeing it characterized, and of interest to a real ( you ) collector. I also found the price wasn't that presumptuous, for the usual over here. It cost me the equivalent to $60,00 ... much less than the garter dagger, in the same seller.
BTW, would you still date this dirk as early 19th century? That would be double comforting, as i mainly seek for age in the pieces i (afford to) get.
Best regards
