So it works great now. I put two scopes together and made this one. I still to do a little cleaning, particularly in the photo tube as there is visible mold that is hurting the resolution. I replaced the 15w tungsten lamp with a new bayonet assembly and 50w halogen which I am not completely satisfied with. Maybe somewhere there is a single LED bayonet bulb I can try.

I have an old-fashioned 3d printer it's called "making things out of wood" here is a homemade photo adapter. It works pretty well but I may want to upgrade my camera eventually. This one is grainy and the sensor is old.
I have as an example a fine slide made by the U of Penna. anatomy student, looks circa 1940s. This is labeled the "Gastro-duodenal junction." and is an excellent ribbon double the usual slip size. I am having a little trouble with the fidelity as seen here, but the scope works well!

40x Planachromat X2 Zoom
I would have thought the zoom would have made a worse picture with the 40x but it is a fantastic objective and produces a good looking picture even at double the size. I put in for the 10x Planachromat I like this one so much. Something I would like to look into is that the photo tube is not parfocal with the objectives. In fact, the image on camera goes out of focus and needs to be readjusted as the zoom is changed which is not the case with the eyepieces (in fact, I like using the zoom just to get a very accurate focus on a particular part of the image and then zoom back out). This probably has to do with the afocal setup I am using, although I will read up a little on this model.
All in all it's a superb scope. Really nice handling, and all the mechanisms are simple to take apart and put back together. It's really big. It's bigger in person. The Balplan uses some similar mechanisms it looks like, but has more flexibility as to the light source and other contrast methods one could employ. For the simple-minded microscopist though, this Dynazoom flat field uses the same lenses and has some very nice features also. For anyone that is interested, I would highly recommend getting a refurbished one from a dealer as they look to run between $200-$300 and I will have ended spending that much on two of these old beat up scopes, solvents, other sundries to get it into good working shape (I merged the best parts from two old scopes). The first scope I had, although it had the head I wanted, I think was used to look at some pretty caustic samples as the lens finish is beat all to hell, the shared rear lens assembly was essentially destroyed as described in painful detail in the Balplan thread, and even some of the paint on the stage base was wrinkled. You never know with this surplus!
