Need help identifying a Wards chainsaw

[KW83]

I just bought this saw for $40. I was told it runs, but who knows. I would like to get some info on it. The one thing I have learned is it has a rusty fuel tank. I tried a picture but it does not seem to be working. Are there any id tags on these things? Thanks

Looks to be one of the run of the mill Mono saws they built for Wards. Not sure exactly which one though. Probably a AH47 powered model

How do I figure out the model ?
