Thanks, Michael. IIRC the Silver 1s are copied from the Suntour Sprint downtube levers. From this diagram it looks like the design of the Silver levers is very similar. But the depiction of the pawl (No. 3, "Ratchet spring A) looks considerably different than the Silver pawl. It could be that other ratcheting Suntour levers contain the parts I require.
The real bear of the Bar Cons is item No. 15, the hexagonal axle nut! There's someone on iBOB who 3D printed some.
