This filter was used with Mr. Corby's Pentacon Praktica Super TL camera. The camera was bought by John Corby, former curator of Industrial Technology at NMST. It was purchased circa 1969 to be used at Mr. Corby's job as curator and was used to photograph most of the images in CSTM's John Corby photographic collection (e.g. Angus Shops, Chesterville Station).
