Hey there team, I have come into possession of a Sig Kadet Senior and I am trying to figure out the manufacture of the engine on it.
It only has markings that say 52 and then what appears to a 7 . S , Im fairly certain that is is not a number 7 but thats what it looks like.
I have attached a few quick shots of it using my phone so they are not the best but hopefully good enough for someone out there to
tell me what it is. Thanks in advance for any information provided!
