They look like some one has saved a lot of Mr Kipling tin foil trays , melted them, shook the aluminium around a bit and poured it into a sand cast. i think i would use them or testing purposes only.
More importantly get your cylinders measured and find out if they are the right size to match another piston make if you get negative advice from other members.

The ring grooves is like someone trying to re-invent the wheel and the notch for circlip access on the piston on the right looks like a lump waiting to fall out. Chinese?

It may be possible to get a "known piston" to fit with a little honing if your lucky. Phone a couple of re-bore specialists and tell them your problem. They may have a stock of piston that they could find 2 for you that will be suitable.
Good luck

I'm guessing they are very old pistons if you look at the piston ring design and they have been machined on the inside of the skirt so might be better quality than we think.

Thank you gents, I'll source some replacements. Safest thing, but look after those, someone might recognise them and they may turn out to be ok. They not Chinese for the Indian air cooled 350 I wonder.
