Need info on the Twin 25mm CA mle 1940J and Twin 40mm Bofors

[hchris]

Hi everybody,

I need info and pictures of the Twin 25mm CA mle 1940J and Twin 40mm Bofors AA (non naval) guns please.

Did a towable Twin 40mm Bofors gun exist which wasn't mounted on ships? I really need pictures of this gun.

Also the Twin 25mm CA mle 1940J, I need everything you can find, pictures and info.

Please post everything you have about those 2 guns, info/pictures about them are VEEEERY hard to find on the net and I am still trying to find a book about AA guns.

Thanks in advance,

Chris

I've never heard of a land-based twin 40mm Bofors: all the twins were naval AFAIK.

I suppose it's possible that a naval mounting might have been installed in a dockyard or something as a makeshift measure, but I've never seen one.

I have recently talked to 2 people who claimed that there was a land based twin naval mount. One of them said he found it in a museum and he will send a picture of it soon.

Interesting - I've just checked the pre-war Bofors catalogue and 'The 40mm Bofors Gun' by Terry Gander (the standard work on the subject) and neither of them mentions a twin-barrelled land mounting, apart from some SPAAGs. And that definitely looks like a land rather than naval mounting.

So who made it and when?

Absolutely no idea, just is just a private photo of somebody who found it in a museum.

About the Bofors 40 mm.

As Tony said, there were some use of twin naval mounts on dry land, but except for a few naval guns installed on trains I don't belive there ever was a mobile twin on land.

The twin gun on the picture is certainly not manufactured by Bofors, and I strongly doubt that it's even designed by Bofors. I don't even think it's a 40 mm, it looks like it's of a smaller caliber. My guess is that it's some Russian copy.

That could well be. The Russian 37mm AA was based on a scaled-up version of the Bofors 25mm, and it looks very similar to the 40mm.
