That's where I got them. It was a box of 100 and I have 97 left! I think I'll put 3 in with each plastic piece I send out just in case people need them, because I know I'll never need that many! This is fun--I've gotten 5 requests so far from all over the country!McMaster sells drive screws. But I assume you would have to buy 50 or 100.
Oh, that brown rectangle in the middle of the red painted plate has something behind it?!? Seriously, thanks for offering the replacement windows.I've noticed that, like the one on mine, the window for the feed display on most mills that people post pictures of has turned an opaque yellowish red and you can't see through it very well if at all. I ordered a 12" x 12" piece of 1/8" "Impact-Resistant Polycarbonate Sheet" from McMaster-Carr which seems to be the perfect replacement (that was the smallest piece I could find at the time). The drive pins holding the brass plate can be driven out from the back. Since I only used a 1 3/8 x 1 7/8" piece I have a lot left and would be happy to cut out a piece, put it in a regular envelope, and send it for free to anyone in this group (in the U.S.) who wants one until I run out of polycarbonate sheet or stamps.

I wouldn't be surprised if ones that are still clear have already been replaced at some point during the last 50 or 60 years and that the problem is one of original porous material + oil + age.I wonder what causes the discoloration of those windows. The window in the grungy old machine I recently acquired is perfectly clear, once I wiped the crud off it.
