4X5 BESELER CB7 and accessories

Why a CB7? Why is the CB7 better than the 45M?

Differences between the CB7 and 45M:The alignment and the alignability on the CB7 is far superior to the 45M. The lower half of the CB7 negative stage doesn't move when you open up to insert negative carrier, resulting in less play and better alignment. The head on the CB7 does not swing up 90 degrees for horizontal projection--for the sake of alignment (there is a right angle projection attachment available for the CB7 to compensate). The CB7 has a geared tilting negative stage and geared tilting lensstage whereas 45M has only non-geared tilting lensstage. The CB7 condenser stage is adjustable on rack whereas the 45M condenser stage is fixed on rack. CB7 oversized condensers assure even illumination. The CB7 lamp position is adjustable to give more even illumination. The CB7 has controls @ front of baseboard. The CB7 has power focus (with fine focus speed adjustment and socket for remote control focus accessory) as well as power elevation. The CB7 has a stabilizer, timer (w/socket for accessory footswitch) and resistrol built-in and mounted at rear of baseboard behind uprights. The CB7 has taller uprights for bigger enlargements on baseboard. The CB7 has generally higher quality engineering and construction. The CB7 is truly a pleasure to use. The CB7 is the only Beseler I would consider for my own darkroom.

Beseler 45M series accessories

Beseler 45M condenser bellows assembly. Note that some parts are missing, notably the focusing knob and the slide locks. What is there is extremely clean. $80. I made 2 of these that were complete with the dovetail geared rail into wideangle view cameras with nifty 2 part revolving lensboards that allowed up to 2" of shift in any direction. The backside may be fitted with a revolving Graflock 4X5 back. The images of the camera are against a green background; these cameras have been sold. I do still have a 2-part lensboard for one of these cameras available for $125. I also have various Graflock 4X5 backs available on my View Cameras web page.

Beseler 45M Nylon bushings for the dovetail rails. If your enlarger has developed too much play in the focusing, these may solve your problem. NEW, $30 per pair. 3 pair available.

Adaptor. Use this to adapt whatever to your Beseler 45M. It is the lower half of a Ferrante Codelite head. The Ferrante Codelite was designed to mount atop the condenser bucket. The square part is 8X8". $50. I have some original literature on the Ferrante Codelite head; you will find that on my Books web page.

Condensers in housing for Beseler 4X5M series enlargers. These are early condensers; later condenser sets came with a filter drawer. The filter drawer is an advantage, but it also allows dust in easily. These older condensers in housing are also very protective of the condensers because the condensers are firmly held in position. Newly cleaned. Mint- condenser set in housing, with a small scratch. $100.

Cold light head holder. This is an early Beseler 45M condenser bucket w/o filter drawer. It is just what you need to set your round Aristo cold lite head down into. The condenser dividers and retainer rings are still inside if you have some condensers you want to install and use this as it was intended. Omega condensers will fit into it. $50. I do have some condensers available if you want to use it as a condenser bucket--see below. You may also use this to hold the variable density diffusion disk listed below.

Condensers for 4X5 Beseler D series enlargers. I have 2 extra sets available. Mint set of 2, $150. Slightly scratched set of 2, $50.

LIGHT BALANCING DIFFUSION DISK, for Omega or Beseler, 6 7/16" diameter, thicker in the center, simply replace your condensers with this or replace the opal plastic diffusion disk supplied with your Aristo or Zone IV cold light head. Think you don't need it? Guess again. Make a flash test by focusing on the negative plane and making a midtone grey print with no negative in the enlarger. You'll probably find that you have a serious hot spot in the center. This light balancing filter is a new item made by GLENNVIEW, available nowhere else, $100. Similar item in 5X7" format, $250. Similar item for Aristo model 810 cold light head, 8.75X10.75" in size, the largest size I can make, $400. Expect 1-2 stops less light ouput with this diffusion disk. The plastic in the 2nd photo has the paper that comes on it as new to protect it. You can see the paper through the edges of the disk because the plastic is thin at the edges. The plastic is smooth under the paper; that side goes down. The machined side goes up. Are you a machinist? Try machining a thin sheet of plastic. You will find it is not worth your time to learn how. I have sold these to Europe's largest photo equipment distributor. I never thought I would be selling a machined product to the Germans.

Let me know if they interest you. In this particular lantern slide, you see Jesus and Judas.

Beseler variable contrast filter kit. Complete set: 1 through 10. Some of the filters are warped. $15.

I am not sure that this is a Beseler filter drawer, but given that it is painted Beseler blue it is a good chance that it is. Probably for a 6X7 or 6X9 enlarger. You may use it for whatever enlarger you wish; adapt your enlager as necessary. $25 each.
