I have also seen a few LAC guns with popped ribs and cracked or broken stocks. Have seen a few that have had missing parts and not just the cocking indicators.
A friend of mine bought an F grade with both hammers missing, the safety missing and the foreend lug missing. Someone had epoxied the forend on and had explained the missing hammers as "the sears needed adjustment to hold the hammers back".
Several years ago I bought an early E grade 11,2XX cocking rod model with pivot top lever that had a rod and spring missing from the bottom of the locking bolt. I didn't know this at the time I bought the gun. It seemed to lock up tight so I took the gun to the range and (with low pressure shells) shot a few clay birds with it. Later, I took it apart to clean 100+ years of gunk out of the action & relubricate when I noticed there should have been 2 more parts.
