I also owed a 8E DM Lefever at one time and sent it to Buck for work on the the triggers and ejectors. He got it working but also said he promised nothing. I don't think he liked working on them much! I have a side plate 20 ga. Lefever with him now for some work.

Here's a nice one in the rare 16 ga. A little pricy though.
