About that new forearm that I just happened to have. Years ago I bought a new recoil spring from Brownell's. It was aftermarket and a little too big, which I found out when the forearm on my '47 split. Brownell's sent me a new one even though I didn't ask. I was able to repair the split and I almost forgot I had this one. Good company, Brownell's. And they quit selling those aftermarket springs.
