Where to find parts/manual for vintage film projectors?
 

Any suggestions on where to find these items. I have been searching online for for a while. Hoping maybe someone will have a suggestion.

Reflector for Kodak Brownie Model 1 8mm Movie Projector

User Manual for Keystone Dual 8 Cartridge Movie Projector Model 441 (Super 8 and 8mm)

Haven't seen listings for either of those models specifically, but Urbanski Film is my go-to source for 8mm and 16mm film equipment, supplies and parts.

Thank you, I had not come across that one. I will check it out from time to time. FYI, the link does not go to Urbanski Film.

Copy/paste error; edited to fix. Thanks for the heads-up.

Maybe not too helpful for OP, though for people in Europe, I know Van Eck in the Netherlands makes and sells projector replacement parts.
