Exa models 1963
The model numbers shown in this ad (from Max Wirgin's company) are not how collectors know them today.
The distinction between the upper two models is between the original Exa (with the script nameplate) and the restyled version Exa I. Both have very restricted top shutter speeds.
The Exa II series all had non-removable pentaprisms and a more conventional focal-plane shutter reaching 1/250th sec.
Oddities common to all include the plump body style, the take-up spools being removable, the shutter release is on the "wrong" side, and a reflex mirror which blacks out after each exposure until the film is advanced again.
