SPIIa - American version with the "eye" for the Honeywell
SMC Macro Takumar 50/4 atttached to it.
It belonged to a retired professor at NC State and he dropped it in my
desk once, together with the 28/3.5 that I also have in my pool.
I don;t hink it was used for more than 10 rolls of film, it was in pristine shape and came with flash, brackets and rolls of Ektachrome 64 that expired in 1976
