[ARC5] Mystery unit

[Bruce Long]

I hesitate to suggest this as I suspect there are many on this email list that know far more than i do about ww2 electronics, but your description brings to mind bombing time intervalometers which provided timing signals to drop multiple bombs are precise intervals.  Perhaps this is a variation on that theme using tone busts and a radio link to synchronize bomb releases from multiple aircraft-   for what reason I fail to imagine.

In going through my stash today, I found a "Signal Corp Time Interval Unit ML-138", MFPed 
in 1944. Looks to be never used. Even has a tag wired to the mounting frame.

Not sure what, exactly, it is, although from what little I can find on the net about it, it includes 
a tone generator.

It is beautifully built inside. All brass-geared clock mechanism in there of some sort with a 
winding key mounted in the lid. There are two main-springs and two places to wind them up 
with.

Would anyone here have a clue...or even several clues?
