Which piston is this? was created by pabdt

I just picked up a 360 DT engine and started disassembling it to check things over and clean it up. Cylinder and piston/rings/looked good.   
The poor engine was out to pasture with literally 29 other bikes.
 
I'm wondering which piston this is. the piston/rings appear in great shape.  Apparently 0.5mm over by stampings.
Has 1 ring.  

No Yamaha markings, but a 36501 on inside of piston.

Thanks for the info.   I asked him for a carb and he apparently stuck a 415 00 on it. 415 Product code shows Euro dt175???? 1973?  Same as USA 74? No 175s at my house….yet 

i think i got shorted on carb.
