Maybe all the parts just drop in. It seems like they should. But it’s been a can of worms for everyone who’s posted about it. Maybe when it’s easy, it’s not worth mentioning. Let us know how it goes. I love Speed Load, but I prefer my guns original. Sometimes I’ll close the bolt, load the mag, engage the cutoff, and reopen the bolt. Then, when it’s my turn, I flip the switch and a shell chambers. You don’t need Speed Load for that.
This might be the last one: the Action Spring Tube. Prior to 1958 action spring tubes were threaded into the receiver and had a tendency to break. So Browning changed to unthreaded tubes that are silver soldered in place. This is a 1930 Auto-5 that had a broken action spring tube: Q I took it Art’s and Nick told me it would need rebluing because the heat destroys the finish. I wanted to preserve the original Belgian Blue so I asked if they could thread a new tube instead. Turns out they couldn’t, but Nick was able to solder the new part without marring the appearance. Since then, they’ve acquired a supply of the original, threaded action tubes.
SUMMARY New Parts Action Spring Tube Breech Block Carrier Spring Extractor, LH Hammer — removed the roller where it contacts the Mainspring, causing galling and FTF’s. Locking Block Receiver — removal of pins for the Carrier Spring, through-holes for Roll Pins, rounded corners, thick tang Roll Pins (instead of screws) Trigger Plate — housing for the new Carrier Spring What have I missed?
Damn! That was certainly a change, and not for the better. I’m not certain it was 1958, mostly they made improvements that year. But I’ll add it to the summary.
Looking at the list, I’ve had most of the problems listed: Action Spring Tube on my 1930 12 gauge. Carrier Spring on my 1957 16. LH Extractor on my 1947 12 Locking Block on the ‘47. When it went, it also broke the Firing Pin. In addition, my 1965 Light Twelve’s hammer broke at one of the lightening holes. The new hammer was lightened differently — no holes, just thinner in the middle. The better hammers obviously came out after 1958, sometime after 1965.
