Gauge, Cavity, Detonator, A/C Bomb No2 Mk1 (1944)

[butterfly]

I got this one today, wasnt sure where to post, but thought it more closely linked with fuzes than the bombs themselves.......so here it is.

The box is marked up

CASE GAUGE, CAVITY, DETONATOR, A/C BOMB NO. 2 OR 7
LEP PART No DDL8806 JUN 1944
REF No 12G/9630857 (12G/1001)



The tool itself is marked up


GAUGE CAVITY DETR A/C BOMB No2 Mk1

F.E.Co 100LB MAY 44

250 & 500 LB


40 & 20LB



The photos below will give you more details on these.

Now I presume that this tool was used for checking the correct space required to insert the detonator into the bomb. What I would like to know is this of American or British origin (I think the former because there are no Air Ministry marks) however I would like to know for sure?
The other thing, would this have been used by armourers, or at a factory when filling the exploder pocket?

I am also curious about the information on the box.......it says No.2 or 7 : does this relate to different detonators IE no 2 and 7 or something else?

I havent seen anything like this before (bomb related) and would be interested to know if any members have anything similar.

One more thing, I noticed a name on the end of the box with a number ; 8545 ROY ROBINSON

Comments welcomed on this one.

kind regards
Kev

Looks like my instincts were right with this one then!!

Were they used by the armourers?

The gauge was used in the arming sheds prior to fitting fuzes and detonators.
If you can get hold of a copy (on DVD) of the WW2 vintage British film 'Rearming a bomber' , it demonstrates how they were used.
Basically to ensure the detonator cavity in a bomb was able to fit a detonator.Could be disasterous otherwise!

Thankyou to all the replies on this one. I managed to dig out a book that I have with a little more information on the use of this tool. I thought it may be of interest to post a couple of extracts.

kind regards
