TOYO 45A broken front standard lock, has anyone seen or fixed this before?

[friender]

Hi all, long time reader first time poster.

So I'm not exactly sure how this happened, but basically the switch that locks down the front standard assembly (Fig. A) to a certain focal length had this washer (Fig. B) come out in pieces, and can no longer lock down. Everything else on the camera is sound, but I am wondering If and where I can find a replacement washer and if anybody here has experience taking apart the front standard assembly. Is it possible to take it apart with relative ease or do I need to send the camera off? Even if somebody has access to a diagram I would be very grateful, I haven't had a tremendous amount of luck finding one anywhere online.




Any help would be greatly appreciated!
