Hi, I'm Scott. I picked up a Thompson T1B14 (Auto Ordnance) this week in a trade. I have wanted one since I was a kid watching Sgt. Chip Sanders on Combat. Hopefully you folks will not mind a few rookie questions. I want to polish the innards a bit and wonder if anyone has a few tips on the best parts to polish? (and what should be left alone.) Any brand of ammo work best for you? I know that the book says no steel but wonder if Aluminum is ok? I have seen a lot of talk about replacement springs and I am wondering what the current best practice is? Does anyone currently sell the nylon buffer or does someone have a template for making my own? What is the thickness? Thanks for any input you may be able to provide.
