Homelite BUZ chainsaw and old MC Culloch???

[slipknot]

I just picked up an old homelite buz chainsaw, and was wondering if anyone knew anything about this saw? when it was made, how many cc's etc.
I also picked up and old Mc culloch that almost looks exactly like it but yellow, no munbers or anything other big "M" on the pull starter. To a collector, anyone know if they are worth anything? the guy said they both run!

For the mac, it may be a model 15, or maybe something similar to that.

got the mac runnin' work on the homie next weekend when I have time! I don't think I am going to keep them, put'm on ebay I guess!

Looked up mac 15 on that site and thats what it appears to be can't find any numbers(anyone know where they are located?) thanks for the help!
