Hello, I picked up 2 old saws. One runs great with serial 54938496. The other is not in good shape but has number 41830 and i think is locked up. Wierd thing is I have a post hole digger for it, and can't seem to find any info or other ones. Have a spare bar and chain, both chains are maked "J". Also have both oil cans and one air cleaner brush. Missing the dogs for the bar, but have the handle end. Looking for any info anyone would have on my new toys. Thanks for reading and hope someone can help me out.
