I have an NC, two Fries modified GC's and a MK II. I have a couple of other (research) cameras that also use Mitchell mags. I've bought various mags along the way, typically all 400's. I probably have a dozen mags plus a 400' bi-pack, all of different vintages. They all fit my various cams, so nothing remarkable. Until now. A couple of 1000's popped up in the last year at a good price, so I bought a few jut for show. However, I discover there are two Mitchell mag-base mount widths. The 400's which fit my NC, GC and MK II and others are 1.940" wide. The 1000's I bought are all 2.200".
The one with the brass throat is a West Hollywood build, the other 1000 is a Gendale build; the inner 400 is a very late Glendale build, and the outer is a Flight Research unit (so built in Richmond VA from the late 80's to mid 90's after they acquired the tooling).
I was always told a standard, NC and GC are the same and the BNCR is the odd one out. But on the other hand, I don't have a standard to test fit, so maybe it takes the wider mag base since it is the earliest design. I was just surprised that different mag sizing has never come up in polite conversation. A B&H 2709 mag is closer to the narrower Mitchell width.
My MK II came with a 1000 mag, but both it and this mag are in storage and I don't have access as I write this. However, I recall it took any number of 400 mags I had at the time, so I think it also uses the narrow dimension. I could continue to speculate all day but clearly someone has the answer. Inquiring minds want to know.
