Wanted: Marlin 336/1894 rear band screw stainless

I have a marlin 336 stainless in 30-30. It is missing the REAR BAND SCREW. I have checked local stores and others online Canada wide. If anyone has one they’d be willing to part with let me know and send a pic please . Or if you could point me in the right direction to find one, that would be greatly appreciated. Thank you. Attached pic is the part I need.
