I grew up bout 30 miles east of Susanville. Went to Jr. college there to get my bone head subjects out of he way. This was back in the early 70's. Was fortunate enough to take a couple of their firearms/police courses. Some of the best memories I have. In the firearms class, as part of our final exam we took our pistols apart (revolvers all) put the pieces in a shoe box and were required to put them back together blind folded. And we were timed on it. Also got to shoot a tompson 45 full auto during the range part of the class. I highly recommend their classes. I was able to customize three guns while in a gunsmith class. Packed the barrels in glass and modified the bolt's on two ruger 30-06's. New stocks and smoothed out the tiggers on them.
Last one I worked on was my Browning A-5 12ga auto light. Won't say what I did to it, but when it was done I did not have to take it apart to chance the plug from 5 shots to 3 or back.
