Spoke too soon - here is a photo and info on NT-49545
http://www.hnsa.org/doc/ecat/cat-1327.htm
and the NT-49620 (8"speaker)
http://www.hnsa.org/doc/ecat/cat-1330.htm
and it's predecessor NT-49131 (5" speaker)
http://www.hnsa.org/doc/ecat/cat-1325.htm
Aha! - I thought I had been imaging things as my 49620 is quite a bit
larger than a unit I had seen shipboard.
