So here I am. Beautiful Model 36 no dash 543575. So I want to remove the cylinder &crane put a drop of oil in . I Use the wrong size screwdriver & booger the screw. I was in a hurry . I was able to dress the screw nicely ,but it`s a thorn in my side to be such a duffer. I order a screw from Brownells, & one from another popular retailer. Both come in ,nice. However both of the screws have threads that are way big . I guess being the genius I am .i cant seem to find the proper screw. any help? Thank you Charlie
