B&O CPL Single Restricting Aspect Lunar Railroad Signal color position GRS

Description

B&O CPL Single Restricting Aspect Lunar Only Railroad Signal.  This is the older steel background with cast iron junction box.
This has been cleaned and painted.  All electrical components have been disassembled and  ultrasonically cleaned.  New general signal  outer lenses.  All new block off plates.  Stainless steel hardware.   I do have the other mast bracket.
Only thing missing is the long bolt or stud to hold cover on junction box.
I don't know any history on this signal.
Local pickup only in Lordstown Ohio.
Thanks.
