Shimano 3 speed shifter- NOT nexus!

I FUBAR'ed a poorly working Shimano 3 speed shifter (Black, with black plastic covered trigger). It's for the range of hubs that were around before the Nexus 3 speed hub and after the Positron/333 generation hubs.

I was reading some previous posts that claim a modern nexus revo shifter will work in a pinch. Is this true? Are there options for a more traditional trigger shifter look? Or where do I look to order an NOS 3 speed shifter?

I could use 3 actually- there are at least 2 other bikes I found at thrift stores that need a shifter replaced for various reasons.

I once set up a Sturmey Archer hub with a Sram front shifter - I figgered as long as the middle gear is lined up, the #1 and #3 gear are just gonna be at the end of the hub's cable travel... it worked pretty well.

I wonder (but do not know) if the Shimano hub would work with a Sturmey Archer trigger shifter... a few hubs were very close copies of their design.

What's wrong with the one you have? Sometimes you can drill and tap the chassis to accept a standard M6 barrel adjuster if you've broken the plastic off, or sometimes you just need a 3/16" bearing!

Edit: I've been told you can also use a nexus 3sp shifter on them, but I've never tried it myself.

The cables work in opposite directions. With SA, the cable pulls the indicator out against spring tension, with Shimano the cable pulls against a bell crank than pushes the indicator against spring tension. The design of the SA flick shifters requires the pull against the cable to shift correctly, so the push of the Shimano hubs will keep it from working correctly.

I'm not saying the shifter will work - if you say it won't I will take your word for it - but it is not because the cable on shimano 'pushes' something - cables always and only pull... you can't push a rope.

one shifter has a missing ball bearing, another shifter has the shoulder where the cable enters completely sheared off, a 3rd shifter is corroded and rusted into one unit. can't split it apart.

But out of the 3, I can probably make one complete. That still leaves me with 2 non functional shifters that need replacing.
