Thank you guys very much!!
I contacted dr5.com yesterday - they look like the best bet for reversal processing. However, they are moving and last processed reversal film back in May! They hope to have a new location by mid-September, but that is cutting it CLOSE to my October date! Their building in Colorado was sold and they are moving out of state. They continue to process all other types of film - just not reversal! They will resume processing reversal film after they have moved - just my luck!!
I also looked at the FPP store, and it looks very promising to use Kodak microfilm 2468! I have a Nikon FM-2 with a Nikon 55mm macro copy lens and a good copy stand. I have used the setup to copy more than 6,000 photos and document pages (many at the National Archives in Suitalnd, Md.) on Panatomic-X and TechPan films. This microfilm seems close to what I have used for copy negatives in the past. If I use this approach, I will have to experiment with exposure times, but can develop with D-76, etc.
The guys in attendance at the historical society presentations want to see good photos. Most of my photos to be copied are in an old (1917) scrapbook, glued on BOTH SIDES of pages made of thick black construction paper. The paper is very brittle and breaks apart when handled. There are four photos per page, all in good condition and fully identified. I think it would be very hard to digitize them without destroying the pages in the book. I did find 125 slides presented at a previous meeting that really look great - hope to add to those with images of approximately equal quality.
