Where to find M48 serial numbers?

[exv152]

I've been able to find 3 serial numbers so far; on the receiver, turned down bolt & buttstock. Does anyone know where i can find other serial numbers on a M48 A, or a good online resource ? I did an online search but wasn't able to find much. Also, is there a way to tell what year the rifle was made from the serial or other number?

Thanks

Floor plate should also have a matching number to the rest of the parts, at least on mine it does. Not sure if any other parts were serialized on a m48. Maybe some of the yugo experts will be able to shed some more light.

Barrel and floorplate also.
