This is a new old stock (NOS) original bracket made by Elmo for the Elmo 16CL and, of course, Kodak CT1000 (a rebrand from Elmo 16CL). The bracket will fit to the lens with 52mm rear barrel diameters such as Elmoscope I, Elmoscope II, Sankor 16D, etc.

It is made of steel not nylon which the currents clone bracket is made with 3D machine. So it is guaranteed very sturdy. 

This is a rare bracket in this new condition. A year ago the same USED bracket was sold in Ebay for £200 (eqv. $250 or EUR 233). So my starting price at £69 is very low.

For those who may not know, yes you can screw the Elmoscope lens onto the main lens, but then screw-unscrew quite hassle if we change the film between scope and non-scope so often. This bracket can be swung if you project a scope film and unswung it if you no longer need it. See photos no 3-5. So this is very useful for projectionist like us.

ps: this auction is for the bracket, scope lens is not included.
