The Rolleiflex TLR (twin lens reflex) medium format range was introduced in 1929, and continued with comparitively minor changes until 1993. The Rolleiflex T (which I have) was released circa 1962.
This book is easily the most comprehensive book on HIT-type cameras there is. If you're serious about collecting these beautiful creations, make sure you grab a copy.
Superb.

This is the lightbox I use to photograph all cameras on this site. Highly recommended.
While the majority of photography podcasts - both audio and video - focus on the gear, in The Art of PhotographyTed Forbes takes a close look at the various aspects of creating great photographs. Everything from explanations of concepts such as ‘rule of thirds’ and ‘depth of field’ to how pinhole cameras work (and how to make one). A tremendous mix.
If you love taking photos, regardless of what type of camera you’re using, whether you’re shooting film or digital; check out The Art of Photography podcast. Highly recommended.
