I think your best bet is to contact NYCSHS and see if one of their collections has the pin drawings. They might extend you a discount since you're a legitimate operator.
Today, my old shop at North Walpole (Green Mt. RR) messaged me about helping to figure out the locking center pin on one of the passenger fleet. The car is a former NYC )opera) baggage car with the swinging end door. The center pin access is from inside the car but the crew was having a time getting things loose and figured out. I had not encountered this style before and am wondering if anyone has a mechanical drawing. It is a variation of the three-piece desing in older cars that hs two outer locking halves with the center straight plate dropped down between them to keep them in place. The NYC car uses a foour-piece where the center plate is a triad and there are three locking castings instead of two. Works exactly the same but just has that different arrangement. A drawing of the four piece would be ideal, as we already have a great drawing of the normal three-piece. Image of the center plate remove is shown here.
