I have the opportunity to purchase a nice looking 1950 Ishapore No1 Mk3* rifle that appears to be original and matching. Not something I was particularly on the hunt for but it looks like a good piece. I am aware of the metal issues rifles of this period had. Anything I should know about these? Sorry, no pictures yet.
If in fact it is a No1Mk3 i dont think there was a metal issue. The 2A and the 2A1 had the issues with strength using the 7.62x51 NATO round
Something else to check into Thunderstreak is if this is a newly Ishapore manufactured No.1 or an FTR'd No.1. Ishapore had a penchant to scrub all previous manufacturer's marks on the rifle body and simply stamping the factory repair stamp over the date post WWII so this will tell you if it is a newly manufactured No.1 or an FTR'd older rifle.

Rather that lose face the Indians changed the proofing requirements so that the rifle 'passed'
All No1s Mk3s were subsequently manufactured until the end of production, using the lower grade steel and were not tested to the correct proof specifications, (the standards were not modified but they were not the tests that were actually applied).
The problems with the 2A / 2A1 was that they just used the new steel that they were using for the Mk3 and it failed diasasterously. They admitted defeat, and changed the steel grade BACK to that specified by the British for the Mk3 and the rifle was just usable but 'operating on the edge'
The internet story that they changed to a superior steel was 'sorta true', but if they hadn't changed to a lesser grade of steel they wouldn't have needed to change it back to that originally specified by the Brits.

Mr Harrison goes onto reveal some real horror stories - one example where the proof house receives some 20 gauge shotguns to proof, but as they do not have any 20 gauge proof cartridges they bore out the chanber to 12 gauge and use 12 gauge proof rounds - the shotgun is then marked up as a 12g.

Thanks for everyone’s input. Alan, I had read that, thank you. Does that affect all 1950 dated No1 Mk3’s or did they change mid year? If so, is it possible to tell the good from the bad?
That said, if it is a bad one, are they safe to shoot? I assume they must be because they were still issued.

Yes they were issued, but that doesn't mean they are as safe as earlier rifles - when tested to their own safety standards they failed, so they lowered the actual test standards to get them passed, but did not amend the 'written standards' or 'admit to the problems'.
If, for safety, the minimum recommended tyre tread is 3mm, are you happy with a dealer says "yes they have only 1mm but you'll be fine, loads of people drive on bald tyres" - what happens when the day comes & you get a greasy, wet road ?
You could argue they've managed to be fired for 50 years without 'blowing up' but as we know stress in steel is a cumulative thing, who knows that it won't fail next time you pull the trigger, or in 100 rounds or 1000 rounds ? The safety factor is lower than all other manufacturers.
For me, a 1950+ Ishapore is not worth the risk, there are 1000's of other No1 Mk3s out there without the potential weakness, at not disimilar prices.
