At the last Switzer's auction, on Oct. 20th, they had an item I never seen before and was wondering if anyone else has ever seen one before?

They called it a "Bren Carrier Pivot Mount". Looking at it's design it doesn't appear to be very large and I am guessing it is used to mount a Bren onto a piece of armour plate. I would like to find one or perhaps more photos of one so I could make one.
I looked at this in your WTB ad and it left me wondering. As well as rotating in the horizontal plane via the pivot above the MK11 marking, it will also rotate in the vertical plane on the front gun mounting bracket pin in the top hole as shown................ So exactly what is the purpose of the hinged part above the horizontal axis? It looks as though it will allow the gun to turn on its side............... But for what?
I presume that the screw-in/out lever allows the tapered thinggy to lock into a recess in a shaft. The down side is that in my very limited experience with guns, the biggest killer of the barrels is heat and the biggest killer of the guns themselves is vibration (the shock-wave after shock-wave after shock-wave after - and on and on) and this screw-in lock mechanism is BOUND to fail during sustained bursts - as sure as god made little green apples..........
Anyone else in forumland got any views?ideas/thoughts?
Yes, that extra pivot point to allow the gun to turn on it's side, is a curious thing indeed. I am starting to wonder more if it was perhaps a prototype that never worked out.
As soon as you turned the gun on its side, the weight would simply snap the thing. I'm sure that some of the Bren fiends will come in soon
I would pressume you would need the hinge to allow the gun to be corrected for upright when on a slope or a hill .Without it you are either going to have to undo the clamp or have a gun firing at a cant.Other AFV,s such as the saracen had a butt rest to stop the Bren waving about when not in use.

Well I no longer need the adapter. I ended custom building a adapter for the person (Dolf) once I found out what he wanted to use it for. He wanted to be able to mount his F/A Bren on a standard 1919 M2 tripod.
The Indian Army have been using adapted M1919 tripods as bren mounts since 1945!
I did not know that. Very cool. I would imagine those adapted tripods would be hard to find?
It looks to have undergone some serious moding. Do you have any other photos kev? I'm wondering if they are new made to a M2/Bren pattern, even the head looks seriously modified, the only unmodified parts look to be the feet.
That is alot more indepth then what I did. I never made an adapter to hold the rear of the gun, as the guy never requested it. I made it fit in the existing 1919 pintle.
Its an Indian 1943 design 'based' on the .30 cal M2 tripod.Tubing of legs is from sheet steel and machining reduced to a minimum so as to fulfill lightweigh spec for para use and simple enough for bicycle works manufacture.Quote:

It looks very similar but I guessed it was new made as there is so much that would need to be modified from a M2 tripod that it wouldn't be worth converting one. I remember Tom B commenting on these quite a while back. I take it you don't have one Kev, it must be on your hit list though! Beezer, thats some nice machining there!
If you like machining mounts I ended up scanning in a lot of the drawings at the Pattern Room library before it was dumped on the Royal Armouries. The complete sets for the Mk I and II Bren tripods were missing from the envelopes of half plate negatives but I copied a full set for the folding Mk 3, the Indian version of the Mk 3, various tree mounts for the Bren, adapters to fit a Bren to a Vickers tripod, 7.92 Besa to vickers and Bren tripods, also a prototype emergency bipod for the Besa along with butt and iron sights, Vickers Berthier to Bren tripod adapter, er what else? At least one vehicle ring mounting for the , Bren, several AA mounts including one for 4 Brens, complete sets for the Straddle and Motley and others I can't remember off the top of my pointy head, Kevin G will know better.
Happy to send them down the wire to anyone who fancies making any of them!

Thanks but I can't take too much credit since the top portion is an actual Bren tripod pintle that I ordered from the UK. The riser is made of a piece of DOM tubing that had just the right ID for the pin on the pintle. I just needed to heat up the tube abit to get it to expand and the pin just dropped it. Once it all cooled down it wouldn't budge. I then turned a V relieve between the two parts so I could weld it up. My original idea was much more complicated but after thinking about it for a couple days the light bulb in my head went off and I came up with this much simpler idea. It has since been parkerized and shipped off to the new owner. :)Quote:

.......Oh the list only gets longer,never shorter !Quote:

Goodness knows how many weeks were spent processing and scaning all the material but Tom is the man for gleaned DDE's (plus heaps of other info) if you need it.
Cheers Tom for making all your hard work available.:thup:

The MoD staff then in charges attitude was if it wasn't pressure bearing or being used for commercial perposes it was public domain so I signed out and copied at home over a thousand sheets of drawings. Unfortunately I only had a domestic scanner to do it with so some like the drawings for the Brens battalion spares chest are very feint ( but if your prepared to zoom in all the dimensions are there),
Happy to share especially when folk are talented enough to make stuff. All I've ever done, well I didn't actually do it all myself come to think of it, was turn a Mk I* cleaning rod and half of a Lewis rod into the two piece Mk I chamber cleaning rod by fitting some new turned ferrules onto the Lewis rod. Oh and cut down a Mk I bren brush to make a Mk I Besa one as per some instructions I found.
