Model K, made in 1935, toward the end of the K run. The trigger control is an early click-type shifter from a few years later. The patent for the first type click shifter (yours is this type) was applied for in summer 1937. This eventually was GB patent #498820. The shifter was announced in 1938 as a new innovation for shifting the 3-speed hubs, particularly the AW (though it probably works fine for your Model K) as well. The trigger was available by spring 1938. However, it was produced alongside the old-style top-tube quadrant for a number of years, with an interruption for WWII. This is an excellent find. The K hub is great, but a trigger shifter made this early is only very rarely seen today.

What kind of bike was this on? Be careful with the large, external flat spring on the shifter. They can be lost or broken easily if they get jarred.

It is on a TOC shaft drive Columbia Model 59; I have the bicycle posted for sale in the Complete Bikes thread. Thanks again for all the information Mike and Pete!

One other point - it's still possible the two components were added together at the same time. We know that there was an overstock of K-model hubs at the end of the run. Although the AW dated to 1936, it was not widely available until 1938. Sturmey Archer made a push to clear out the stock of K-series hubs made toward the end of the run in order to make way. So if you have a bike that was converted to a 3-speed in 1938 or 1939, it's entirely possible someone used one of the newer "click" shifters but used a late K series hub because the AW was not yet available in quantity.

So does a sprocket hub work with a shaft drive(?); some kind of interface adapter?

I don't know Archie, below is a link to the bike. I believe the correct Columbia chainless hub gear was mounted to the Sturmey Archer in place of a convention sprocket. All that is hidden within the dust cover. Pretty clever...
