No, unfortunately, I can't. They are actually photos posted by others that I saved just because they interested me technically (and, as you noted, had the different tooth forms). You might try a search on "transfer gears" (here and in the old site archive), and sift thru those threads to see if you can find the original posts and see if the original posters included any further details in the text.
That's a wonderful slide valve arrangement there. Who made it for you? PM me if you like, didn't mean to derail the thread!
User STRATOS from Switserland on this forum has acces to the gearsets, see this older thread http://ferrarichat.com/forum/showthread.php?t=43891
Another good photo of the helical cut version from STRATOS in that thread (so thought I'd add it here just to double the chance that someone who needs it might find it in the future ): Image Unavailable, Please Login
An engine's story... Just recently purchased a 308 (288 body) ferrari to go classic racing. When viewing the car at the restoration workshop that had been holding the car, the workshop owner (Gxxx) introduce me to his friend (Dxx) who had popped round. His friend also runs a race workshop and was heavily involved with IMSA back in the day. So whilst chatting to Dxx he recalled having a 308 race engine in a crate at the back of the workshop that had been there for a few years. So armed with some photos and a call to the engine shop that had looked after the engine during it's racing life we gathered the following. It was the spare engine for a Spice GTP car Engine was original developed and built by Michelotto The 2V engines raced in 92-94, this one did 2hrs. The engines were mothballed when the QV variant became available. Spec CR 13:1 fuel 110Oct HP 410-425 RPM 9000 ECU EFI Tech (long lost, so we will use Motec) Crank standard Rods Carrillo Pistons JE Apparently the QV variants were even more crazy, pulling 9800 and over 500hp The engine guy, is going to pull out the records when he next gets into his loft, so that should help substantiate the history. Which then gets me back to figuring out what bottom end it should sit on.
I think you'll find all the Euro racing transmission parts came from Colotti ; I spoke to them several years ago; they were invloved in the sand castings of the P and 512 prototype transmissions. Long standing history of working with Ferrari. http://www.colotti.com/ http://www.colotti.com/Engl/ferrE.htm cheers! Here is the link to Michelotto in Italy; they have a deparment specifically for transmissions; should be able to order the parts directly from them. http://www.michelottoautomobili.it/english/pagine/pag-contact-it.html cheers!
