Title: NMG-1 Underwater Sound Equipment
Post by: Mark Sarsfield on December 22, 2010, 06:21:09 PM

Has anyone ever heard of this equipment?  A speaker for the unit is listed on eBay... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260669932628

It does not look familiar to me as far as WWII boats go.

Well, like most crap on eBay, they say its WWII and it's NOT... but this is probably Guppy fleetboat-early nuke vintage. It probably is a bridge speaker or trunk speaker. Pressure proof speakers are mounted in these locations. Hope it has a drain in the bottom. But they didn't include very good photos. I'd pass on it.

You misread the tag.  It is NMC-1

This is a WW II depth sounder speaker.

Sorry about that.  Still, this does not look like the fathometer gear on any of the WWII museum subs.  Was it used on surface ships?
