Bill,
Those are great photos, thank you for adding them! I am confident that my assessment of the toggle lock modification is correct…pressing the knurled top “button” allows the latch to be disconnected without pulling back on the toggle. The large extended button on the takedown lever makes it easier to rotate the lever for disassembly/assembly. The modifications are clever additions by a relatively talented gunsmith, either for himself or for a client who may have had arthritis or some other problem that made it difficult to operate the functions of the gun…or he may have done it just as an exercise in improving ergonomics! At any rate it is an interesting piece and I have enjoyed seeing it.
