Hammer extension for older Marlin 336 QUESTION??

[SuperCub]

Just bought an older 336A for a fellow at work. Am scoping it for him, but need a hammer spur.

Uncle Mikes lists two types of hammer spurs for 336s. 1957-1982 and 1982 to present. This rifle shows DOM at 1956. Ser# is P198XX. Hammer measures 0.280" wide.

Any one have a 336 (1957-1982) that they can measure the hammer to compare to mine?

THANKS!

The hammer on my 1974 Marlin also measures 0.280" wide.

Thanks. That helps a lot. Not sure why Uncle Mikes lists those extentsions like that.

0.280" sounds about right

I've got these two sitting here collecting dust. PM me if you would like one.

My 1975 Marlin hammer spur is narrower than the 1985 Marlin I sold to a hunting partner.
I liked the newer one better as it sat lower and the butt of the hammer didn't roll over it.
The only conclusion I could come up with is the newer cross bolt safety made for a
wider hammer, hence the wider gap for the spur to fit over.
This is my experience, and not sure whether other developments made things different.
