Why Not an RE Auto Version?
This is the R Topcor 200mm f/4 lens carried over from the R Topcon camera system. While the optics are superior, the lens is heavy and the hood screws into the filter threads rather than telescoping. This lens was also designed before the advent of the RE Super/Super D camera, so there is no coupling to the camera's exposure system. The diaphragm is of the preset type; and, with the RE Super/Super D, exposure readings must be taken at the shooting aperture. The cylindrical tripod attachment is a little odd-it juts out at a right angle to the optical axis, is sturdy enough; but, neither the camera attachment bayonet nor the tripod shoe, allow rotation. So, for vertical format, the tripod mount itself must be rotated. For hand holding, I find the tripod shoe gets in the way.

Loader for Bulk Film Magazine
Manual loading of the cassettes for the Bulk Film Back would be a chore without this handy loader provided by Topcon. It has a shaft to hold the supply spool (up to 100 feet), another for mounting the cassette spool, and a mechanism for metering the film onto the take-up spool in pre-selected lengths--50, 100, 150, 185, and full capacity of 250 exposures.

Before loading begins, the length to be loaded is set with the lights on. When the lights are extinguished the supply spool is mounted, the film threaded, and film metering sprocket engaged, all in the dark. The little crank is then turned until it stops. At this point the film is cut and the loaded spool is assembled into the two cassette housings. Then the film remaining on the supply spool must be protected before the lights are turned on. This would be an interesting operation in a change bag.

The construction of this device is somewhat unique in that the base and vertical member are made of nicely finished (hard?) wood. This is the way things were done in the 'good old days', before the advent of the ubiquitous plastic.

Last of the Navy Topcons
Maybe the last of the line, a second generation Super Dm (serial number 722XXXX) in full military dress. Attached is a Navy zoom lens of the final type--no tripod attachment and with a new serial number sequence (10XXX). The Navy eschewed the CC finder, opting instead for the standard pentaprism.

On the decorative ring, the red 'N' identifies this lens as one modified specially for Navy use.

Many Topcons were used by Navy pilots who were not the most conscientious of photographers. Since most shots were focused at infinity, a lock was added to hold the distance ring at that setting, allowing 'grab' shots without the trouble of focusing. Pressing on the front end of the lock released it and allowed closer than infinity focusing. 

A handsome combination in basic black. Most Navy Topcons had 'U.S. NAVY' engraved at the factory on the bottom plate, but examples are known where rather crude hand engraving was employed.

Motorized Copying
Shown here is a studio setup for production copying. The camera, with Motor Drive, is mounted on the Topcon Copy Stand with power supplied by the AC Adapter. The black button at the top center of the Adapter controls exposures and below it is a small slide switch to select single frame or continuous operation. The white button at the lower left is the power ON/OFF control.

An RE Auto Topcor 35mm f/2.8 lens, with hood, is mounted to the camera. This is superb copy lens with little distortion, a flat plane of focus and sharpness, at mid aperture, to rival many normal lenses.
