Part of B&Os laboratory and workshop instrument series.They produced a vast range of instruments, many of which were used in theirauthorized repairshops (back when things got repaired).They are also often referred to in service manuals.I have collected the instruments and I use a good handful of them in myown little repairshop.
The NM1 is used for measuring signal/noise ratio (among other things).

Jeff,
you've been watching eBay! There are lots of power supply units too from B&O workshops in the US.

@ Dillen.
Do you by any change have the service manual(s) from the RV10, RV11C and DM1?
These need some TLC and some adjustment
I have many but they are not yet indexed so I'd have to run through the piles to check.

Dave,
Right you are. I spotted this Signal/Noise meter on eBay and thought it might be a useful tool.
