110 Enlarger mask for? Aperture measures 16.2mm x 10.45mm so close to the 17 x 13 of 110 film but maybe not. The guide rails for the strip of film are 17mm wide. Anyone know what enlarger this fits? A Google Image search didn't work. 35mm film cassette not included, there for scale. 

WHO WE ARE: Oddog2 is a husband/wife team, home-based small business specializing in the buying/refurbishment/selling of primarily photographic equipment. We do occasionally have other types of things to sell that come to us as a result of our search for camera-related items. We have over 50 years of experience with photographic equipment, both as a shooter (17 years newspaper photojournalist) and as a collector/restorer/seller. We have been on eBay as Oddog or Oddog2 since September 1999.
