Two questions:

1. Wurlitzer used a very fine brass mesh as a lint filter under
their removable tracker bars.  Is this material still available?
If so, where can it be purchased without having to buy more than
I need (for tracker bar lint filter purpose)?

2. Is #18 gauge wire adequate for those 1/8-horsepower Holtzer-Cabot
motors so commonly found on pianos?

Thanks,
Dave Krall
