This

is a set of for extension tubes marked 4/3/2/1.5. The bayonet on the

front of the no.4 tube accepts a standard 50mm Contax lens such as a

Sonnar. The rear bayonet is approximately 45mm diamter, and is made

to fit inside a mount. It may look like a Contax EXTERNAL bayonet,

but it is a bit smaller and is an INTERNAL bayonet.

It

is beautifully made in nickel finish on brass. The engraving style

and the quality is typical Zeiss, but there are no logos or code

numbers.

I believe they are Zeiss Ikon Contax  Extension Rings for Special Reproduction Apparatus 5520/1

I

sell my spare cameras as collectibles. I try & describe

everything as well as possible, but most have not been tested with

film.
