Are there any Belgian proofmarks on the water-table / frame? I'll offer some general musings that might not approach the value of a Wooden Nickel but all the marks are on the tubeset. Too, that double underlever platform is seen on Germanic type offers, well maybe moreso Austrian, up till the 20th Century & a little beyond. If there isn't a Perron, etc., on the water-table, does that point to a manufacture @ some other gunmaking centre? Are there any stamps on the standing breech?
Cheers,
Raimey
