Since I last posted in this thread, I expanded my Beseler Topcon family to include the three levels of product which they sold during the mid-60's.
As a young teen, the Beseler Auto 100 was what I had available to shoot with, at $159. Desire was strong for the almost affordable Beseler Topcon D-1 (just out of reach for our middle class family at $269), but it was outright lust for the unattainable Beseler Topcon Super D ($420 with f/1.4), the world's first SLR with TTL metering on the mass market (as the Topcon RE Super). In today's dollars, the Super D was $5300 (using the price of gas as the comparative number). It took me 47 years to finally own all three!
And my son-in-law provided me with this Fotron for my recent birthday
