Dischargers, smoke generator, 4 inch

[Larry Mass]

Just wondering if the bracket to mount the smoke discharger to hull is cast, it kinda looks like it on photos. Has any one reproduced these or have an original that they might want to get rid of.

Yes, the hull bracket on the MK-I* is cast. Bronze. Hence few and far between of the originals exist. Ben H. had copies made circa 2012/2013, in woodpecker lip cast steel. The MK-I* bracket is not interchangeable with the MK-II*.

(I am reliably advised by a good friend that original examples of UC MK-I and UC MK-I* smoke discharger hull mounting brackets can be found in steel) Kia ora L.E.

While the Quebec made Ross M-10 .303BRIT action was used for Canadian Universal Carriers, the MK-I* was remotely fired by attached cable, while the MK-II* was a conventional 'finger on trigger' release.

Do you mean the Mk1 and Mk2 bracket Lynn?

Mk2 is fitted inside the gunners armour and a different shape to the Mk1. To my knowledge they were always made in steel. Ron.

I have a complete MKI discharger c/w original bracket and cable etc. available in the buy/sell section.

[Lynn Eades]

Thank you Ron. That's what I wondered about. My Canadian MkI* one is cast steel.

Larry indicated in earlier posts he has a 'MK-II' carrier.
The Canadian MK-I* smoke discharger bracket is not used on the C31UCW NO-2 MK-II* carriers. The brackets are dissimilar.

This is how you will normally find the cartridges for the launcher.

Good news: I had Clive scan the booklet from cover to cover and now have a PDF file that I can email. If you want a copy, simply

Feel free to share it with your friends, but not for redistribution for commercial means.

Hi Folks,

Thanks for all the great info posted so far. Hopefully quick question here. Does anybody know what the original diameter is for the hole which transmits the ballasite (sp?) round's force from the breech, into the cup discharger?
I hope the wording that question made sense. Thanks - Chris

It's the same size as the rifle's bore so .303 on an Enfield or Ross rifle. With virtually no barrel they wouldn't want to restrict the cartridges gas emission on firing. Recoil would tear the device from its mounting.

Chris.

Nothing fancy as these dischargers were all based on some form of a .303 cal rifle from which the breech and small section of the rear end of the barrel were retained. There were no modifications done to the bore diameter. The Ballistite cartridges were designed with more than enough power to get the job done.

I suspect you might be thinking of blank firing adapters that are fitted to the muzzle of automatic weapons to permit a gas pressure buildup in the barrel of the weapon to enable the action to function properly. Trying that with a Ballistite cartridge would be outright dangerous.

Thanks guys. So if I'm reading this correctly, we're saying the original hole size through the adapter is about 5/16" which is close to .303? - Chris

I'll measure one of mine and get back to you.
I have one without the canister barrel on it right now.
Stay tuned.
cheers,
Warren

addendum: THIS IS FOR THE ROSS ACTION.
the barrel ID is .305 in. and a barrel length from the witness mark of 2.68 in.
