I was going through my grandfather's B&W negatives from the 30's & 40's and figured out that they are mostly 116 2.5" x 4.25" size. Does anyone know if Beseler ever made a negative carrier for their 4x5 enlargers that would handle this size 116 film? If so do you know the product number? Otherwise I guess I'll have to use a 4x5 glass carrier and mask off a bit. Thanks!
