It looks great Ray. In my opinion, you always want a topcoat. Not necessarily for a shine, but to protect the piece. Dust tends to stick to an unfinished surface more that a finished piece.
That is the first EX after the design change. Made by Excalibur. It’s probably close to twenty years old. It will probably need new bearings and sleeves. Current parts should fit. $400 is way too much. Might be a good buy at $250.
