Your brush cap appears to be the same size as the little R&M 8" universal and DC motors take.  It's either you go to the BST and cross your fingers someone has a bomber out there to part with a cap for you, or seek help from Darryl Hudson to reproduce one, or a set for you. 

I tried in past to seek a replacement for one of my 8" models on the web.  McMaster Carr has a threaded black nylon thumb screw with a knurled thumb screw that closely matches the knurling and diameter of the R&M brush cap.  The problem was the largest threading offered for this nylon thumb screw was 1/4-20.

Good luck.
