This is NOT a discussion of which type of construction is best. My question is, when and what company first started using cast receivers. Some wise man said that the Winchester model 20 in 410 built in the 20's had a cast reciever. Don't know. That got me wondering. Did the early 1900's cheap single shots had cast receivers. I read once that it was only when Thompson Center started their company, that casting receivers was perfected. Does anyone know?
