I was emailed this image from a friend whom is doing research on WW2 Hong Kong. Could anyone help identify the bike, the British used the Thompson machine gun during WW2 as I have found one while metal detecting in Hong Kong. The rig for the machine gun looks complex but also a production item not one off.
Stuart, your photo is one of a series taken of the Grenadier Guards at Swanage in the late summer of 1940. A series of publicity photos really, intended to put the fear of God up the Hun and I've no doubt that it achieved its objective as shortly afterwards, they abandoned plans for 'Sealion' and began bombing the industrial cities where formidable fighting machines such as the Model 18 Norton with 'Cow's Udder' silencer were made !
The most likely source of the Model 18s was a small batch of 7 bikes marked in the Ministry of Supply ledgers as 'already delivered' in August 1940; Presumably built from factory stock, including the obsolete 1938 pattern silencer (which Norton reportedly dropped mid-way through the model year due to customer resistance). They probably had a storeroom full.
I don't believe that I've ever seen a clear photograph of how the mount was fitted to the motorcycle at the rear of the fuel tank, but it's probably reasonable to assume that the rest used parts taken from existing vehicle mounts. Elevation was controlled by a nasty-looking ratchet / detent device positioned just where it would split the rider's difference in the event of a tumble.
Thompsons had been present in France with the BEF, although not in great numbers.
Many thanks for all the valuable information and my apologies for not keeping up with all the threads Ron, to busy preparing the old girl for the Hong Kong classic bike club show on 11th November, a few military vehicles will be turning up as well so Ill take lots of snaps to post.
Only joking Stuart! Only benefit of being old, is not having to go to work anymore!!
Horror (from this forum) is building a WD Model 18 from all WD and period parts. It would be good to see his progress and whether he intends to replicate that silencer. Ugly as it is.....I would still want to fit one.:slightly_frowning_face: Ron
Norton (who had made their name with rather rorty machinery got drawn into the late 1930s obsession with silence, smoothness and clean lines but were never very good at any of it...One of the books has a sectioned drawing of the '38 silencer and it's quite well thought-out internally. It was fitted to all models, including the Internationals and those machines where the purchaser paid an extra £5 for 'Competition' (Trials) spec with high level exhaust.
The silencers were catalogued in right and left hand versions for the twin-ports - Imagine two of those at high level. Guaranteed to keep a flapper's inner thighs warm :slightly_smiling_face:
