Does anyone have a mainspring for a 431? Rolling Eyes

People you thought were your best friends will stab you in the back to your face!

Love them anyway.

Tomas, The 448 material catalog says 430-439 are interchangeable with the 431. Jules Borel doesn't list it but they do have 440 springs in stock.

430-431-435-440 size 1.15 x .11 1/4 x 235

Jules list the 440 spring size, 1.20 x .11 x 240

Close enough for government work.
