Sanwa OSBN-24, but with different thread pitch?

[ArcadeMachinist]

I wonder if Sanwa OSBN-24 (screw in) buttons thread pitch was changed one day?

Red button you see here (picture from eBay) on the throttle lever is OSBN-24, with Sanwa marks, etc.
But... it has smaller thread pitch, so newer OSBN-24 won't fit the joystick.

I wonder if it was some custom order for SEGA, or just someday Sanwa did change the pitch on their buttons?

can you take the button apart and marry the old outer shell with the new guts?

I did exactly that.
But outer shell has signs of wear too, including cracks, which I fixed.
Just want to know for the future rehabs.
