This is an open concours forum, not a critique of your for sale part and YOU ASKED !
You can try to sell a $30 knob for $500 all day, no one cares. You only embarrassed yourself. People might be interested in what’s correct in the concours section.
If you don’t like the reality feedback, post in the lounge with your friends. Why didn’t you attack Bob Gaines when he said the same thing? See reply 5
Regarding restoration, sure you can do it. Tell me how many cores you want at $500 each and I will send you a box full.
