Accessory bracket for mounting
The mounting plate attached to the housing of the Range Finder is designed to accept the battery cases of the Kalart Master Speed Flash and the Folmer Graflex Flash Battery Case. To facilitate the attachment of battery cases of other manufacture there is available an accessory slide which fits on the mounting plate and is secured with one screw. The special shoe supplied with most of these other battery cases can be attached to this slide instead of to the Range Finder housing.
