What John said, I personally never saw one used on an SLR. If you are really wanting to print some the dimensions would not be too far off a Bren magazines size if not exactly the same. In 1/35th I would think it would not be noticeable if there was a difference. I think I have an old Italeri accessories set with Brens in them. I could certainly measure one or even send one to you as you would need to get the curve angle right also.

Keith, although you said 30 round mag - do you mean the box mag with a slight curve to it ? If so, that was the standard mag for the LMG and when they were ever fitted to SLRs we had to have the mag spring reinforced to push up the rounds as the LMG springs are gravity assisted as they were top feeders. The standard SLR mag was a 20 round box mag.
To be honest, for realism I would go with a 20 round mag if your using it on a UK SLR as the 30 round ones were rarely used unless someone wanted to look a bit Rambo ish and as said we're only used if you had the spring reinforced otherwise it caused stoppages.

Their is also a Straight 30 rd SLR Magazine used on the L1A2 Heavy Barrel AR support weapon (not used by the UK but used in Australia, New Zealand and I believe Canada). the Magazines were dead straight and came in Bren Magazine Boxes. We also had L4 Brens and interchanged the Mags and I never once suffered any stoppage due to poor Spring compression. Funnily enough in my last Field Posting we had mainly Bren Mags for our L1A2's until they were retired in 94!
