Wanted: WANTED BOLT FOR MOSSBERG 385 20 GAUGE SHOTGUN

Hi

I am looking for the back half of the bolt (with firing pin installed), or a complete bolt for a Mossberg 385 series 20 Gauge shotgun.

Picture of bolt for reference. If you have a bolt that looks like this but don't know what it fits, contact me. I can provide some dimensions.

For an incomplete rear half, the parts I need are numbers 13, 17 and 24 on the parts schematic.

I'm told that a  385KB, 385T, 485T, 390KA bolt will also work.

Thank you

Nick
