stamp counterfeits

Hello friends,
Has anybody here heard about a stamp trader called Mauro Spada from
Faenza, Italy? He has sent me some stamps pre-1960 because of an exchange.
None of them is postmarked, but some do not have gum. The ones that have gum
have their gum intact, like new, I think they're regummed. i find them too
new to their supposed age. I would like to know about your opinions.

You can see one of them he

I can scan more if something is interested in checking them

Thanks in advance,
Pedro
