WESS MOUNT PRODUCT NUMBERS The product numbers used for Wess slide mounts help describe the product. For example, the first three alphabetic characters indicate the mount size (film type), registration, and glass configuration. The second set of three characters are the aperture code (such as 002, the standard) and, in some cases, indicate a special feature. For example, an AAA002 is a 2x2" (5x5cm) slide mount with registration pegs, A/N glass, and a 35mm 002 aperture. An AGX002 has the same aperture, but is a 35mm General Purpose (GP) mount without glass.		*For a specific aperture, please contact us at BCA Manufacturing, Ltd., and someone will assist you in getting you what you want.
