From a British War Office ‘Technical Intelligence Summary’ No. 154 published on 29/11/1944.
The item shewn is said to be a “Projector found in a coast defence repair shop at Boulogne” No ammunition was discovered with it and the somewhat flimsy sights were noted as being stored within the projector for transit. The hollow mounting tube was meant to have been slipped over a ground mounted spigot.
To abide by the rules, does anyone have a picture of the rocket involved and/or a picture of the thing in use?
Happy collecting, Peter
