Yes it is.

This the way it was designed.  The woven cloth is there to cover the Allen 
machine screws that secure the resonators to the plate. So purely cosmetic.

Probably not since 1986 Vintage

No.

Harold Conklin did more research on tuned and detuned duplex's than any one 
I know of.

Lifting the strings will reduce the amount if sizzle quite significantly, 
so try before you braid anything.  Make sure the the lower shoulder of the 
hammers in this section is deep needled, to give the hammer some elasticity.

Hope this helps.
Regards Roger
