Rubber and paint

[Radio Fixer]

Thanks for replies.  Think I will start with Sam's suggestion.  Working in the Philips Cap (the dial assembly that pivots) is very difficult and this might be the easier way to go.

Also the replacement Eye (been in stock for years and now almost unobtainable) is different having a recessed front end so keeping out light from the sides.  Both have the EM1 name.
