For a while I had a Winchester 1890 with a GECO Model 1919 barrel pinned-and-sleeved in, with the 1890 rings soldered on the bottom. Was probably a Great Depression job where labor was cheaper than parts.

After a botched re-sleeving job, I sent it t Corelokt here and between us we found enough parts to bring it back to original condition, its my niece's 10th birthday present.
