[TenTec] Omni Series Panel and Trim Ring

[k7mks at comcast.net]

Starting to restore an Omni D Series B and have a need for a cosmetically nice front panel or a method to redo some letters or numerals that closely match the original. 

A previous owner went wild with an engraving tool on the trim ring and my options are to find a parts rig for a trim ring 
or to find some way to sand and fill the groves he cut and then repaint the trim ring. BTW - how do you get the trim piece removed. 

Many thanks joe k7mks
