WWII radiation counter

This is my first time posting on here. It seems I can't post URLs for a week because I'm new so photos will have to wait.
Can anyone tell me about a radiation counter that I've been shown. It was purchased at a garage sale some time ago by a woman at work and I told her I'd try to get it appraised for her. The pouch is clearly stamped and dated 1942 with the broad arrow in a C and seems to have been made for the device.  The wand is brass and stamped 'Eveready'. There are four spare tubes and a plastic 'Radiac Calculator No1' wheel. It uses the phrase 'atomic explosion'.
Either the Canadian military was prepared to deal with atomic warfare in 1942 or the counter was made to fit an existing bag.

An image would help.

Considering the fact that Atomic warfare did not start until 1945 and that the Manhattan Project was one of, if not the most closely guarded military secret of the Second World War, then I think anyone would be safe to hypothesize that the item you are describing is post WWII.

PM sent, I will post the photo's for you if you can send them to me.

Of course the majority of members here will recognize that the bag shown is actually a gas mask / respirator carrier. Therefore the date on the bag is in no way related to the contents and can not be used as an indicator of the age of the contents.

I did not recognize that as as a gas mask bag but I will now. I like Canadian web gear for it's own sake anyway. The counter then, is the mystery I need solved. Can that be dated and has it any value to a museum or collector or is it a common item?

The radiac calculator is British issue but that's about all I can add. I have no clue who used the meter nor when. I suspect it's not military but that's just a gut feeling. Good luck with your search.

Doing some quick research, it seems that geiger counters were mainly produced from 1953 into the 60's. Yours would seem to fit that age. The Radiac wheel is British issue as Infanteer has pointed out. The tubes marked Victoreen, are US, they manufactured geiger counters for civil defence use.
That leaves the question of the counter itself, it appears most US ones were in yellow cases. The British ones did have unpainted radiac counters. Perhaps yours is British or its lost its case at some point. It is lacking the carry handle which would have been on the case as well.
Eveready was US company, so that could mean its US.
The other oddity that I've come across is the scale on the meter. Most geiger counters didn't measure milliamperes and the scale was not 0-100.
I couldn't find your exact model, but googling the manufacturer on the tubes helped and you can search US patent numbers too I believe.
Perhaps theres more information on the parts of the counter I can't read.

I would take a guess and say there is a collector market for these, but I can't see it being a big market or worth big bucks.

There are no other numbers anywhere else on the counter. The etched lines on the top plate makes it look home made. It would be interesting to find out if it still works. My wife works at Waterloo University. Maybe the physics department can check it out.
