Well Tom, what you want is easy. I can post as many Surmene pictures as many you wish, as they are plenty here in market and offered continuously on internet. Seller says this one is 41 cms. A big one with some silver inlay. Perhaps I must pay more attention to them and collect some while they are still not expensive??
.
I just think, both the pinky finger pad and the unsharp edged tip are to support and strengthen the thrusts. By "Tartaric",you mean Crimean Tartars or Middle Ajia? On which samples does the pad exist? Or both?
regards
