Winchester Model 21

[Researcher]

I actually bought the Ned Schwing Model 21 book back during the 34 year gap I didn't own one. About $25 on the used book rack at my local pawn shop. Probably a better buy than any of the guns!!

Used hard cover copies of the book are about $250 on ebay

Cylinder and modified is actually a fairly common combination for prewar double trigger 26" 21s. Prewar Model 24s were also commonly bored cylinder and modified in 26" models. The Model 24 26" guns were changed to improved cylinder and modified after the war.
