Either a Webley Mk 4, these should have a 6 inch barrel and were private purchase. From 1913 Webley Mk 5 there may be a number of * after the number, basically a beucratic %%^** up. Or a Mk 6 . These are rated at .455 Caliber, the Webley man stopper round, although the calaibre is actually slightly diffrent at .441. Unlike WW2 I can't find any reference to US models being used. Officers could purchse theier own pistols provided they chambered the standard .455 round. The Webley & Scott Self Loading pistol Mk1 were issued to Roayl Horse Artilley drivers and Royal Flying Corp. These had a diffrent round to the revolvers. at .456 inch Be aware a lot of the Enfeilds sold as .455 are post war, often dated in the 1920's.

The diode is a valve, current flows one way. As you say earth short is the first thought. Easy to check diode with multimeter. Most have a diod check on them, if not set on ohms. Current should flow one way, not other. If the diode has a band on it, that (If theold grey is stilll working) is the + end.

Could be a version of the home grown Davidka.

Make an offer for the cost of a repro.

Yeah, thanks for a masterclass in split repair.

Welcome along Colin.

I think the prototypes were knocking about in 1939, and a few of the first production.

Welcome Andy.

Welcome in, anyway 7's do have a military heritage.

Do the valves have markings on? Post some of those and we may be able to trace back.

Welcome in.

Your still welcome. There are a lot of moddlers here. I for one am in awe of their skills.

Does that go with the 'Stores are for storing, not issuing'. :-D

Welcome, New Zealand seems to have a thriving MV scene.

Welcome Jen.

One very common cause of sudden faliure in thermionic valve equipment is the valve heater circuit. In a lot of stuff it was a series circuit.

There are several Great War Forums. Depnding on what specific intrest you have . Don't be afriad to ask seemingly silly questions here. I do all the time, it's how I learn. I'm sure Jack is happy to expand his Empire!

Welcome in! Thats a great find.

Yeah yoppe! But not everything is in the manuals. A lot of knowledge is assumed. It was a time mechanic did more than change a black box for another one. :pfrt:

There are some god ceramic and resin type materials available now. Such as these. http://www.alvinproducts.com/

Heathen! People you like Wouldn't even know about Ivor the Engine! Hi John, even if my roots are from the other end of God's own country.

Actaually ! Why not ? A crib sheet of symptoms and possible causes can be very useful. Spongey brakes- check fluid adjust shoes etc. Or particular funnies associated with certain vehicles. Such as drain the oil on a 101 V8, pack the oil pump with petroleum jelly or it won't pick the oil up again.

Welcome Alan

Welcome along.

Welcome!
