Good morning;
What a response. I had no idea what sort of ideas, suggestions, comments, recommendations, (and even corrections) and encouragement would result from describing this "retro" or "period" photography effort, "The 1960's Nikon Project." Thank you. Clearly this is not something that I could do alone. You are providing the information needed to make this not only real, but also true.
In looking at my own resources, I do indeed see that the Nikon Dealer's Handbook I have is dated in the late 1970's; mainly 1978. Yes, the SB-7 is later, but it is still a nice electronic flash unit, and it does work. Probably the correct one for that time, the SB-1, will not be easy to find. Oh, well. Even trying to find a replacement Honeywell Strobonar 600 (or the later 660) and the 510 volt battery pack that I had then is not easy. I do recall taking some very long range flash photographs with that flash on TX-400 film at f 1.4.
John had suggested a source for the Nikon SB-7 bulb type flash gun, but when the shop owner was approached, he said that he did not think that anyone would want "that kind of thing," so all three of them were thrown away. This is the kind of thing that makes working with older equipment a trial at times, and it also gives the emotions a bit of a roller coaster ride.
For the folding flash gun that I had (another of the casualties of the death of a marriage), I had obtained a little two inch parabolic reflector plug-in bayonet base AG-1 bulb adapter to go into the flash gun socket. That reflector was stripped of its silver paint, polished, copper plated, nickel plated, base chrome plated, and then finally lustrous chrome plated. This produced an optical system that gave me every bit of light available from the AG-1 and AG-1B flash bulbs. It worked quite well. I was proud of the optical qualities of that adapter.
If another Nikon BC-7 Flash Gun becomes available, I will remember the kind offer of something to feed it.
Again, for the suggestions and encouragement, I thank you.
Enjoy;
Ralph Javins
