I inherited an ~1880's Bailey 9 1/2 block plane, type 4 or 5 as far as I can tell (details below). It has a problem w/ the blade depth adjustment. I think the lever may be damaged. I'm not totally sure what the nub is supposed to look like, but I suspect it isn't engaging the blade very well. Whatever the case, the blade only moves when the nut is on the top half of the adjustment range.
For the life of me I can't find a part number or anything specific about the depth adjustment lever. I can't even figure out how to get it out. And I'm having a hell of a time finding a place to get parts for this old of a plane. Does anyone here know where I could find obscure parts for an obscure plane? Or how to get the arm out of the plane?
Plane details: The only identifying marks on the plane are stamped into the iron: "L. Bailey's" Patent "Aug.6.67" "Aug.31.58 EX'D". It looks like a 9 1/2 type 5-ish block plane to my amateur eyes... 1880's. It's apparently been in my family since before WWII. It works great, when I can get it adjusted.
