Jason: Thanks. The "91 - 4" stamping is the date, then? I have no idea if the "5" stamping refered to speeds or some internal part that has five features (eg: improvement over the old part that only had three; or some such). Good to know what it is. Now I can research ratios. Ratia?
OK, now we're talking. Typical biker scenario. Have one little bit so, need to build up an entire bike from it. Not unlike archeology when a fleck of dinosaur is developed into a behemoth skeleton. Jason: Apologies if I double-posted.

Sounds like you have a Sturmey Archer five speed hub. By 1991 SA probably had changed to using two indicator spindles. Try threading an indicator spindle into each side of the hollow axle. If this works, next you need two three speed shifters. The right shifter works as a typical three speed shifter. This will give low, normal (1:1), and high. The left shifter selects normal or wide range. Since normal is the same for either normal or wide range, you only have five speeds. With the left shifter in normal, you have what is pretty much like a normal three speed hub, but with the low and high a little closer to normal. With the left shifter in wide, you have a lower low and a higher high. I don't remember exactly, but I think that you use 1 & 2 positions for the left indicator.
Hope this helps, Jason
