WTD SA 4 speed shifter/ bar end shifter

[mellon farmer]

bit of a long shot but does anyone have a working 4 Sturmey Archer speed shifter? Looks like they are hens teeth but you never know. If not a friction bar end shifter might do it, not sure if the left might even do- depends on the pull needed.

What was wrong with the one on the bike.jm.

I think there is a spring missing from the pawl- the lever does not 'click' for each change and there is no retention for the middle gears. What about the bar end shifters?
