Re: Military Battery - DRY HT/GB 90/7.5
Hi Tim,
Can't quite make out the third set of NSN numbers on the battery. Being only 90V would probably indicate something low powered like a receiver. The only one that comes to mind to me is the MCR1. The battery date is quite later than WW2 so it could possibly be used with the post war MCR1 made in Belgium by MBLE. It uses 90v for ht and 7.5v for lt/gb. Another possible use is in test equipment. The "99" in the number indicates a UK origin so can eliminate most US stuff. What is the pinout for the socket? Bruce |

Re: Military Battery - DRY HT/GB 90/7.5
Hi,
But exactly what is 'UK origin'? I have a British military watch with the 99 in the NSN , but it is marked 'Swiss made'. Kind regards Dave |

Re: Military Battery - DRY HT/GB 90/7.5
The 99 is the NCB (National Codification Bureau) number. It usually means country of origin or manufacture but not always. It is the country that introduced the product to the NATO supply system. In this case it was the UK.

May have been used in a radiation survey meter.

Re: Military Battery - DRY HT/GB 90/7.5
The common white No1 meter uses two 150v batteries. It uses valves, but they're all cold cathode and don't need an LT battery.

Re: Military Battery - DRY HT/GB 90/7.5
Found some photos of MCR1. The "mains" PSU shows the socket, is it like yours?
