Getting to the bottom of an old anti-aircraft gun

[Arigrand]

Dear Sir or Madam, I am a researcher of modern anti-aircraft artillery. Recently, I came to know about a 57mm M1936 anti-aircraft gun from the Swedish company Bofors. When I tried to delve into the details of this anti-aircraft gun, I was stopped by the scant mentions in professional publications. Now, I have come to this forum seeking your help.

Are you sure it's 1936 gun, and not Bofors 57 mm m/47 aircraft gun?

Yes, sir or madam, I did see a name regarding Bofors anti-aircraft guns: 57mm L/60 Model 1936, but I haven't found more information about this type of weapon. So now I'm starting to wonder if I might have confused it with the 40mm L/60 Mo ...

Or maybe I saw false information, because the project I'm currently researching is related to the 57mm Model 1951, an anti-aircraft gun associated with Sweden and France. What I want to do now is trace the origin of this type of anti-aircraft gun, and then I came across a guy called the 57mm L/60 M1936.

I tried to find anything about Bofors pre-war 57-mm guns, but seems that this caliber wasn't used much. One possibility - maybe it was a rebuild of some old cannon for high-angle mount, given a new designation?

Thank you, you have given me a new research direction.

I mean, 57mm was a common caliber for anti-torpedo boat weapons, which were relatively fast firing. Then it picked up for bigger Antitank guns (6pdr and ZiS-2).

But 57mm is relatively uncommon as an AA weapon. The cases designed for AT guns happen to give high muzzle velocity, which makes them desirable for AA.

Multiple 40-45mm mounts like the USN Quads are better for close-in AA, and replacing them with 3"/50s was happening post 1945.

The usual step for ground AA was hand-swung 12.7mm-23mm, then directed 37-45mm, and finally heavier stuff, 75mm, 90mm, even 120mm under radar control.

The gun existed, even as hardware. It was even considered by the Royal Navy, before WW2, as a double naval mount, Boeing rejected because of that. This is what I know.

枪支存在，甚至只是硬件。二战前，英国皇家海军甚至曾考虑将其视为双舰用支架，但波音因此拒绝了。这是我所知道的。

谢谢你，这对我意义重大。

Can I ask you if this cannon is related to the 57mm M1951?

I believe it was it's first iteration. BTW, my first post mentioned "Boeing". I meant "being".
