Black and Decker 6" Junior Bench Grinder Polisher (Vintage - possibly 1950s/60s?) NVR upgrade

A random look at my vintage bench grinder / polisher which may date back to the 1950s / 1960s. As you can see from the video, it is in excellent cosmetic condition and full working order. The original rubber coated / sheathed wiring was deteriorating and so it was trimmed back to the windings and new tails fitted. You'll also note that I added an NVR switch which I consider to be much safer than the latching toggle switch that was previously fitted.
