[Hallicrafters] SX-28 Bandspread Dial Stringing

[Joe Connor]

Does anyone have or a know a source for a dial-stringing diagram for the bandspread dial on an SX-28?Mine broke today. I've found diagrams for the band-pointer mechanism but none for the bandspread dial. 
 
The good news is that the geared main tuning works so well that I rarely have had to use the bandspread on an SX-28. However, out of a sense of completeness, I would like to have the bandspread working properly. 
 
As always, thanks for your help.
