Winchester 1873 22 rimfire cartridge stop spring needed|Restoration, Repair and Maintenance|Forum|Winchester Collector

I have a good friend who is having the 1873 inner magazine woes. It appears as though his inner magazine tube is entirely missing the wrap around type cartridge stop spring. If anyone has any way to source this part, it would be greatly appreciated. This is a .22 short if it makes a difference. Please message me or email cnafab at gmail . com thanks!
