Hi Richard:
The Rolleiflex T with Xenar lens is referred by
Prochnow in the Rollei Report 2 _second and reviewed 2001 edition_ ,
it's the Prochnow Register 185/2, PR 185/2. The T with Xenar 3.5/75
lens was manufactured from the beginning of 1973 to August 1976, 3000
units from serial numbers T2.310.000 to T2.320.449.
Rollei specs for Xenar and Tessar lens were identical and then the T
Xenar is at least as good as the T Tessar in theory.-
