I'm not sure this is a prototype of Polgar. A prototype of Polgar would make more sense on Polgar hardware.
But what else should it be?
If not Polgar, then probably a prototype of Academy (if its date is earlier) - I see no other Schroeder engines that are similar to this T+T.
I think it will be the best to just call this T+T 'prototype' instead of 'Polgar prototype'
