Does anyone recognize this plug?

[Brownac1983]

I'm planning a restoration on an M5 generator set from 1943. These were used to power the director for the Bofors antiaircraft gun. I want to use it for power, but I don't want to have to modify it if possible. In order to build an outlet box for it without modifying the gen set I will need to match the original output plug. I found a picture in the Bofors tech manual of what the plug should look like, but I'm not sure where to find it or even what it would be called. It looks like a Cannon or Amphenol plug but it has a separate gasket insert. I've attached a picture, if anyone recognizes this or has any idea where I could find one please let me know. Thanks in advance for any help.

What gauge wire do they take?

I'll have to measure it when I get back in town, but it's pretty large wire, maybe 4 or 6 gauge. Whatever this is, it's different from the MIL-DTL-5015 plugs shown there. This one has external pins with no shroud surrounding them. On all the newer mil spec connectors like the ones in the link the male pins are surrounded by a shroud to protect them. This one is basically flat face to face with a removable rubber gasket between the plugs.
