Recently I got such a shifter with the marking ST-A050. It looks cool and works fine. Nowhere can I find information about this model. What group Shimano, what year of release - Google can not find anything. I write here in the hope that someone has information about this model.
P.S. And forgive me for my awful english.

I think you'll find it's a flat-bar road lever/shifter combo. It may say the bar clamp size on it?
Should be 3x7 speed shifting, so more for touring/trekking/hybrid use I guess.
I'm not sure what level it is, but probably lower end of the Shimano groupset range, think of Claris sort of level.

If you search Google there's a few hits for ones for sale/sold on ebay.

Eg... https://m.ebay.co.uk/itm/Dual-control-s ... amp;_rdt=1

This shifter looks like Deore DX, and works no worse.
⌀ 22.2mm

The shifter is the same as used for the 100GS through to the deore LX for the 1992 model year.

100GS is the same as Tourney. I don`t understand. You want to say that the shifter from 100GS was screwed to the body from Deore LX?

Essentially the same shifter unit was used, yes, the differences were in the materials used for the brake levers, as the shifter unit just bolts onto the lever assembly.
