mystery pistons

[H/O84]

So i was recently given a set of 20 over flat top SBC 350 Pistons. I have tried to do some research but have not been able to come up with anything. The only markings on them is P-1505, M-19A, and IND BRAS. The number matches an engine tech number but those are dished Pistons while mine are flat top, so it is not those. Any one have any idea ? not sure if I will ever use them but they are in really good condition and I would like to know incase I ever need them. Thanks

Enginetech P1505(8) Piston Set dishtop 85 buxx for a set of 8

Sounds like a set of boat anchors to me

They are not dish top pistons. They are flat top with 4 valve reliefs

I see dish tops in the link Alabama posted. My Pistons are flat tops.
