Haganah - TMT IV Sten markings

[Flying10uk]

phillb, are you asking, is the taper at the start of the chamber to aid feeding or are you asking for the sizes angles etc and other dimensions? If it's the former the answer is yes.

With 9x19mm the throat is the unrifled part of the barrel bore directly in front of mouth of the case. It is where the bullet sits. Another name for the throat is freebore. The tapered part of the barrel directly in front of the throat is called the lead.

Not quite F-10 (thread 10). The taper or shallow lead-in you show is deliberate recess for the extractor so that the barrel can be inserted in any rotary position without it needing a separate extractor slot or fouling the extractor. In a Sten, the bullet is 'aimed' or directed at 8 degrees right from horizontal where it will (hopefully, with a non drooping mag housing etc etc) enter the chamber. The round nose assists this, not(?) that chamfer.

I completely forgot about the need for recess for an extractor, thanks Peter. pilb, are you able to give us some clarification as to exactly what the question was that you were asking in post 70, please?

i was just wondering why there is a recess , ive now found out after a fair bit of trawling through usa sites that its 120 degrees ..thanks all

I seem to have collected a few sten mags, various markings

l/h side.....SA N45 X2, N45 MB1..................

R/H SIDE....M/13 ,S/14 ( ARROW ) , N93, E&Co, I.C.R.1, S68, L, SA S18, STAR OF DAVID *

any rare ones ?

[Flying10uk]

The examples with the viewing holes in the side are mk1 mags (un modified) and without holes mk2. mk1 mags are said to be rarer than mk2 although there does seem to be a few turning up on the surplus market. Looks like you have 3 modified mk1s with the viewing holes filled up with solder/braze. The mag 3rd from right and the far right mag in 2nd picture look like Indian reduced capacity mags (19rnds?).

Nothing unusual that I can see.

There’s a chapter on magazines in Peter’s excellent Sten carbine book.

The number of books available is getting low, so if you want one… His Sterling book has been sold out for a while and the prices have tripled.. if you can find one.

5 sten trigger mech covers, 3 x mk 2, 2 x mk 5

only one marked is the L.B. one.....second from left is brazed the entire length both sides, field repair ??

yes ive got peters book

[Peter Laidler]

There was/is another TM cover variant of the shorter Mk5 gun type. It is a conversion/modifiied longer Mk2 type whereby the sides at the front end have been 'docked' and rounded then the underside has been rounded to suit the new curvature. Then gas welded to suit.

Someone with a bit of time on their hands should write a book solely about the variables of the parts. Especially the magazines where some 68,000,000 were made
