When 11 yrs. old , Dad and I took my new "sporterized " 6.5 mm Sweedish Mauser out for the first day of Pa. buck season , 1959. It was a steady light rain all day. I remember the European birch stock of my Mauser going from Linspeed brown to white , as the five coats of BLO washed off. After the wet gun dried off a week later , next to the coal furnace , we used another type finish , which is still on the rifle today. Think I might get that little kids gun out and use it this season. It's a killer. Back in the early 1970's , when there was little to no available knowledge on gunstock finish in my world. As a trial , I had built myself a .58 cal. Jager rifle w/ an English walnut stock. I decided to try a tung oil finish,. I literally soaked it w/ tung oil mixed w/ Japan drier , and let the stock dry for a couple weeks. Months later , took the flint rifle out on a damp light all day rain in the Pa. mtns. , for deer. Since it was ice storming , I wore gloves , and where I held the stock , the finish wore off that day. Just another failed experiment by a young builder.
