[PRD1]

Boy, did you come to the wrong shop! I lack both equipment and expertise for making and posting photos.
However, I did order just the rearmost toggle segment (which features the cocking knobs AND the needed rear sight, and discussed the operation with Lugerdoc, who confirmed what I believed was the proper procedure:
Drive out the small retaining pin at the left-hand end of the rear pivot pin (upward), then press or drive out the pivot pin itself; right-to-left - reassemble in reverse order - apply creative language as and whenever necessary.
I've got hammers, punches, and, should it prove necessary, an arbor press, so am anticipating a successful operation. I'll let you know...
In addition, I spent some time this afternoon disassembling, cleaning and reassembling one of my wood-based Luger magazines, according to the instructions provided by G.T. (you would not BELIEVE the amount of corruption and gunk which came out of that magazine): the patient survived the operation and I only needed one medium bandaid. My advice: send your magazines to G.T.!
