Right side 1889 parts

[Jennick]

I am in search of a right side mainspring and tumbler. These are the last Parts I need to complete this build. Parts have been difficult for me to find. I was directed to the Remington Society. Hopefully someone here can help. Thanks in advance.
1889 16ga. Mfg in1900. Grade 3.

Very cool restoration, not too many 16's show up! Are you sure your parts needed aren't cross over to the 12 gauge? I have a 16 gauge grade 1 for reference if need be.

I might have the parts you need. And parts from a 12ga. gun should work. The main spring is the same for all gauges.
