Tomorrow I may dig out the bellows and slide copier and see what happens using Delta 100 as a "copy" film.Bill
I found other starting points. Technical Pan; Kodak 5302; Kodak 5360.
5302 is very slow (about 1 iso) but also very cheap (15$ for 100'). See

About Technical Pan, from Larry Ackerman:
In my opinion the best film for making positive slides from negatives is Kodak Technical Pan Film 2415 (Cat No 129 7563 for 135-36 rollls and 129 9916
for 150 ft rolls) developed in Kodak undiluted D-19 for 4 Minutes at 20 o C. You can also vary the developer and conditions in order to adjust the contrast
range--see Kodak Publication No. P-255.
From Phil Rutledge: I used to use Tech Pan rated at ASA 125 and got beautiful slides. Used a Nikon on automatic mode with an aperture of about f:6 on a 90mm lens. Use a good light box. Developed in D-19, 1:1 for 3min, fixed, washed and dried. In the past I used type 4489 EM film for my slide. Tech Pan works rather well for making B&W slides from Negs.
About Kodak 5360 film:
DIRECT MP FILM 5360 One step reversal film!
35mm perforated film. For the production of black and white direct-reversal duplicates of continuous tone or line material with a minimum of time and work. 5360 can produce lecture slides easier and faster than other films by the reversal process. D-19 can be used for development, 3-9 minutes with continuous agitation at 20oC, with stop bath for 30 seconds, fixing without hardener for 2-4 minutes and washing for 20 minutes. However, Dektol 100% for 7 minutes can also be used at 21oC, agitating by 3-4 tank inversions in 5 seconds every minute followed by normal stop, fix and washing procedures. Direct MP film 5360 provides intermediate contrast which can be controlled by adjusting
development time or temperature. It is coated on clear 5mm acetate substrate. A tungsten light source is suggested. This is movie film stock which is cut to a shorter length and repacked with permission from Kodak. 30.5m/roll

I have been looking for the right combination of film/exposure/developper on the net and have never found anything more than a few vague words. A knowledgable photographer made the deduction that Tech Pan would be the best and that this would ask for a lot of experimentation to set the proper exposure and development time combination (given the proprietary developer for pictorial photography would be used). I have a few rolls a Tech Pan in the fridge and some developer but I just cannot find the time to experiment (working on that...) So I keep looking for The Recipe. On my side, the B&W negs I'd like to convert to slides are mainly contrasty Plus-X in D76.> Andre
