I have an Eastman Kodak "Mini" Enlarger and the only "identifying data" is the patent number and that it is a Model 1. I bought it from a friend in the mid 1970's but never used it! Now, I'm wondering if it is something that I should pass on to my grandkids as an heirloom, sell on e-Bay or Craigs, donate to a museum, or just put on the shelf as a decoration. Does anyone have any idea of its value to a collector or ????? Thanks in advance for your help.
