pistons?

[Calamity Josh]

Been offered these pistons cheap, there vauxhall viva ones, either out of the 1159 or 1256 (i'm being told tomorrow) a few questions:
would people say there forged?
what other vauxhalls would they fit?
and would they be worth a buy?

I would hazard a guess at them being cast
Probably just OHV engines...not sure
No unless less than £20
