1. The one piece barrel lug with the tapered back end is necessary for use with beavertail forends. Otherwise, with a square back end lug, there is a tendency for the solder to loosen and the forend will come off during shooting, particularly when bearing the weight of the beavertail forend. Repros all had the one piece lug, whether beavertail or splinter forend. The pictured lug looks normal.
2. Repros and Ilion made Rem original Parkers have a moisture weep hole through the bottom rib adjacent the barrel lug. It was left unplugged. See TPS for photos.
3. Suggest you partially disassemble the forend mechanism by removing it from the wood. The latch parts should be apparent without further taking apart the ejectors . See that the latch parts move normally and that the ejector hammers seat normally . Suggest you thoroughly clean the mechanism with Rem Action Cleaner and then sparingly put drops of gun action grease on the moving parts.
4. I have seen suggestions here that carb cleaner is as good as Rem Action Cleaner. While I have not tested it, I was informed by Babe Del Grego that they do not recommend carb cleaner because of a tendency to migrate and carry gunk, and then to solidify, whereas Rem cleaner does not. As a result, I use gun specific formulated Rem Action Cleaner and it has worked well for me. I have also seen recommendations to oil the action parts. In my opinion, oiling the the double trigger parts and very sparingly oiling the single trigger parts when assembling is correct , but after that, light gun grease is superior to oil because oil migrates and grease stays. Excessive grease will collect crud, so keep it light. I always grease the locking bite where the bolt fits and the hinge surfaces, then wipe off the grease when cleaning after use.
