I really don't think KC intended any insult or ridicule , tupenix .
I've been posting here for some time and the only ridicule has been light-hearted , irreverent & between members here who are familiar with each other (with the exception of giving Hell to 'spammers') , IMO .
It's not too unusual for folks to post requests/questions about unsigned/unmarked items of some antique value .... the difficulties in discerning the values & authenticy of such items are sometimes manifold , esp. when all we have to go on is an image .
Plenty of times a member here will come up with the right answers , but not always .
Commonly , when members here 'draw a blank' , or are unsure after researching a posting , they'll suggest that a person go to a local source/dealer , for a hands-on inspection of their item .
