Marlin 39A Golden Boy front sight

I picked up a Marlin 39A with the plan to shoot it as a dedicated open sight hunter when the weather is too shitty for scoped optics.
Unfortunately, the previous owner butchered the front sight and I need a replacement. Can't seem to find a replacement anywhere in NZ, even a universal one.

Anyone got a spare in the draw they would be willing to part with, or anyone got a 39A who can measure the height of the original insert so I can order a universal one out of the USA with confidence that I have the correct height?

Cheers guys.

Front Sights

might do the trick

Cheers mace08 - I should have thought to look at Skinner as I already have one of their units on my rossi lever ……..
