I saw this interesting interchangeable lens outfit on Ebay:

I found some information that the Anticomar was a tessar type lens. The Tele-Peconar (not pecomar) is a zoom type lens. But I'm not sure what the focal lengths of this one would be. The Heli-Orthar (not Orinar) is the wide angle. Not sure of it's construction type.

I was wondering if anyone has ever used this type of camera? At the price I suppose it's more of a collector's item. Just wondering how lenses compared to the standard Zeiss Tessars of the time.
