Lithgow with welded locking lugs?

[SandersBallistics]

Hello all,

I have a Lithgow receiver I purchased recently while cleaning it up two areas became highlighted. The rear locking lugs appear as though they have been welded.

Would this have been a repair or done at the factory? I read somewhere that Lithgow welded these areas and them quenched the receivers is this true?

I am not sure if this picture will work.

Perhaps heat treatment to harden the shoulders?

[Peter Laidler]

BP is absolutely correct. It is the induction hardened locking shoulders. The only hardened part of the body.

We used to test the hardness of these shoulders with No4 and 5 rifles undergoing Base Workshop repair using the old IZOD impact hardnes test if anyone remembers that very simple and visible method of testing. Not that old really......, still in use at Uni in the 70's!

Thank you for the replies. I was initially worried that someone had drilled it out and re-welded them.

Now I know I should not really use it as it is also stamped DP

Hope you didn't pay too much for it.

I bought 4 rusty receivers for $100 including shipping and transfer fee. Probably not that great of a deal, but at least the others will be usable.

The bolts and other bits will end up costing more, would have been cheaper to buy a sporterized rifle and rebarrel that!
