Linhof Serial Numbers

[Embdude]

Hi Bob,

80087 B - Appears to be a III with the black leather and 4 back locks but it has a B below the serial number and the corresponding 3 Zeiss lenses with it. I had thought the B versions with the Zeiss lenses showed up with the IV in 1956/57 but perhaps they appeared on the later III's at first. I know the IV had a larger front standard opening to accommodate the Biogon so if this camera is a III B type then apparently the larger front standard hole likely first appeared with the III B variant.
