1. I know, I have 3 now. One rifle, 1938 Ivesta, and 2 carbines a 1943 bladed and a 1956 spiker
I did find out that it only took 2 gallons of gasoline per rifle.
I would recomend that you remove the stock and set it in the sun for several hours. This is to leach the remaining cosmo out of the wood.
