Hello MMD!  My Gulbransen Recordo player has a Motor Player Corp.
vacuum pump and Electora unit.  The pump is inside a wooden box
which, I'm ashamed to say, I haven't inspected for a long time.
However, inside the box the pump is packed in what looks very much
like sawdust, just as Brian Butler found (MMDigest Monday,
