I bough this antique brush with a pewter handle. really great look to it. I had no desire to restore it. That is until i stupidly picked it up by the knot and the knot fell out . So Ive decided to restore it. The knot size i believe is 18. anyone dealt with a pewter handle? if so is adhering the knot going to be the same process. also what knots would you use? thanks in advance.
