identify stihl chainsaws

Bough a stihl for $50 can't seem to find the model on the saw or find a serial number to identify would wonder if some one recognizes it from the pictures

I have two stihl saws that I was told were ms362 however they are missing parts and do not have any badges, the serial number on one is 282543786 and the other is 279795567. I didn't want to replace anything until I was sure of the saws. Thanks for any help
