skilsaw model 77

[azshadeguy]

I am looking for some parts on a skilsaw. I can't seem to find the right model number on the parts page. The model number is a 77 not the HD77. serial #1B504000. This is an older saw. What I am wondering is if the the parts are the same? What model number is the closest?
Thanks Paul

I had a saw just like yours, but parts were getting harder to obtain, alot of the parts are no longer available. But I do have the parts list. Ill attach it here.
Good luck!!
