Marking on 1945 No. 5 Mk 1

[Tatanka]

Somebody I correspond with has acquired a very nice 1945 No. 5 manufactured at BSA Shirley.




It bears a marking that we just can't identify: 3 dots on the receiver, close to what seems to be an Australian inspection mark.


Any ideas as to its signification?

The last two No5s I had, had these punches. I would love to know what they meant myself....

[Patrick Chadwick]

Hardness test?

[Peter Laidler]

Definately won't be a hardness test mark. That part ain't hardened!

[Brit plumber]

Does the astericks mean corrosion in the bore or cordware or somthing like that?

[muffett.2008]

My interpretation would be.....the asterix signifies a barrel/chamber defect.
The subsequent inspections were marked with dimples, three marks should have signified the part was still defect and had not improved and should be replaced.

[Peter Laidler]

Markings that affected the barrel say, would be be on the barrel because later, another examiner/Armourer/Inspector would judge it to be worthy of replacement. Rusted out No5 barrels - both inside AND out were commonplace. Barrel would be changed but if the defect mark were on the body, then the next bunch of Armourers would be scratching their heads looking for it. At l;east the Z or BLR marks painted onto a butt could be scraped off and weapon sent back into service. But marks punched into the body stayed there and in any case, the only place we were allowed to stamp the body was at the butt socket. Just my practical take on things.

I seem to recall that our crack test mark was a triangle mark and the hardness mark was a diamond that straddled the impact mark or vice verca. But that's going back and testing my memory now....

I think the asterisk is a depot inspection mark, and the three punches are probably re-inspection checks. I reckon the No5 has been in a weapons pool or theatre loan stores somewhere, and each of the three punches is a check when its come back into the pool from a unit.

I think Muffett has it. I recently serviced a No.4Mk.1/2 with a big ugly U/S, (unserviceable?), stamped on the top of the receiver. I'm guessing many of these marks were applied after British service by India and other Armies to whom they were issued. The original bolt also had a big half moon ground out of the top of the handle to clear a telescope in an aftermarket mount at some point because I had to replace the rear sight as well as fit a new bolt. The only thing I found wrong with it was a badly bent and chipped striker. I used a new striker and had to fit a #0 bolt head to bring the headspace back to spec. A plus since it had a #2 in it as original. It fed, functioned and shot a ragged hole on the 25 yard test target so it's good to go now.

[Tatanka]

So far, I think the suggestion that the punch marks were applied when the weapon was returned to theatre stores is the most likely.
Thanks. If anyone comes up with documentation that would be great! (unlikely though...)
