If you trip on over the jouster.com Enfield forum you can ask Peter Laidler. IIRC he recently said there that there was no use of silencers that he was aware of, on the No4(T).
There are anecdotes suggesting the British used them in WWI on occasion, but I have never read anything suggesting on what rifles.
Gen. Currie, commander of the Canadian Expeditionary Force in WWI, is quoted in "Without Warning", as requesting the purchase of silenced .22 Winchesters for use in sniping. Similar to what was of course used by the "British Resistance Movement" in WWII, perhaps by SOE as well, I don't know.
I was suprized to learn that at one time France had laws that anyone who owned a .22 rifle or pistol within city limits had to buy a silencer for it.
Don't know the exact time period but this was mentioned in the information accompanying a presentation grade Colt Woodsman pistol made for a Company big wig in Paris, that pistol had extensive engraving with Gold inlays and the silencer in the same fitted case was also engraved and inlaid. Nice staghorn grips too.
A local store had a Winchester pump action .22 with threaded barrel and a thread protector in place. By the time I'd tracked down information on this model it had been sold.
These were ordered from the factory with matching silencer. The ads say to kill foxes in the hen house without disturbing egg production.
Funny thing I found out in my younger days is that if you fire a pistol with silencer within twenty feet of a half empty Kerosene fuel tank the sound of the muzzle report which you would not otherwise hear can be reflected back at an audible frequency.
You can't eliminate all the sound waves just the audible frequencies. Dogs can hear stuff we can't.
Remember Uncle Sugar frowns on experimenting with suppressors so look into the laws before messing with them.
Not sure but I think there are places in the UK were Silencers are legal if you have a good reason to use one, horse breeders use silenced shotguns to eliminate pest without spooking the herd.
I'd like to see an effective moderator, I'm not interested in silenced shots just moderating the report to avoid hearing damage. I enjoy my music too much to go shooting without both ear plugs and hearing protectors, but I don't like not being able to hear whats going on around me.
I may still have an old set of Sionics earplugs that were suposed to filter out damaging vibrations while allowing you the hear normally. They don't work well enough though.
Theres a Wolf Ears head set that does this electronically.
The OSS had a commercial Mauser 9mm Express pistol that had both a fitted barrel extension and silencer that could be used eith as a pistol or as a rifle.
The barrel extension used tapered threads and each was indexed so the lands matched up.
