Does anyone have anything on the British Projectile fuzes made by Graseby Dynamics?

The nomenclatures are:
GD 81-160
GD 51-160
GD 76-175

I am also curious to know if anyone has any fuzes made by Graseby? I know the code is GD, but would like to see one if possible.

GD is more than likely the filling factory - ROF Glascoed, now BAE Glascoed.

Graseby Dynamics made explosive detectors then diversified into Chemical and Biological warfare agent sensors. Now part of Smith's Instruments.

Graseby Dynamics were formed by the merger of Graseby Instruments and Pye Dynamics. when they merged Graseby moved from Tolworth to the Pye Dynamics site at Bushey.

Pye did some of the early VT fuse work. Possibly if Graseby Dynamics made fuzes they were from the Pye side of the company.
 
Robert Constantine Graseby (Griesbach befroe WW1) was one of the three founding directors of "Venner Time Switches Ltd", who did produce timers for fuzes Their patent GB569715-applied for in 1940 covers a time fuze to be applied to a shell, incorporating an anti-disturbance feature, and thus designed to sabotage a munition dump. Oddly they also held several wartime patents for electric fence energisers for defence purposes!
Graseby Instruments Ltd were formed in 1944 at same site to make and refurbish naval sonar equipment. Thus TimG more than likely is correct in stating ROFGlascoed is signified by GD, as Dynamics did not join up with Graseby Instruments Ltd until later.
