Does anyone know for what reason this sear bar spring is brass plated
(I think it is plated, as to my opinion you can't make springs out of brass)
The spring is in a byf 42, and looks absolute original as is the whole gun.
I have never seen this before, who can tell me more ?

Strawed?

Your spring might fit but is not original colouring, should be blueish in colour ie ( heat tempered spring steel). If the spring works then it is as villiers stated, it is strawed and a bit off at that.

Strawing is a heating process that changes the original colour of metal to a golden colour like straw in the fields at harvest time. You will see strawing on mid/late 1937 lugers but not on the sear spring.

You are right about brass, it is to soft for spring steel.

No I don't think it is strawed, the color is too dark for that, it really looks like old brass that's never been polished, and it doesn't look like a home made spring.
I don't know anything about the history of this Luger, it's used as you can see (65% blue)but in excellent condition and with a mint bore.
I think, I will replace the springfor a blued one !!
Thanks

By the way, the spring works perfect.
When you are heating steel it first becomes straw then blue, so if it is straw from the heating proces I'am not sure if the spring would work properly
