For those interested in Peter Meyer's workshop manual for the ENV preselector gearbox the latest news is that there have been holdups but the book is expected to be published in a few months time.
My only interest is as an avid enthusiast for this make of preselector and who is looking forwards to purchasing one of these manuals in due course. Chris.
Thanks for the update, I will also be buying on of the manuals. I have a copy of the one on the Armstrong box; the information is certainly very detailed.
