Old organ drawknob

[chchaisson]

This organ stop just came in from eBay; a choir tremulant. It's in great condition, but all we know about it is that it's from an "old organ."

Anyway, just wondering if anybody knew what kind of organ this type of drawknob would have come from. (tracker, maybe?)

Does not look like it came from any of the turn of the century trackers. My guess is electro-pneumatic, 1930s vintage. Possibly Skinner.
