Hello people,   i have a small chainsaw, Husqvarna 135.   i know the type of chain i need for it and even the file type and angles to file.. but there is just no where online or anywhere that has the file size and usage table for my chain. The chain says 37 on the drive links (the chain is 3/8pitch, 1.3mm gauge, and 52 drive link) .. i want the kind of table you get on the back of a chain box just for reference. but that number "37" does not show up on the only two chain identification chart
