Perhaps the evolution of the 200T I suppose .I imagine it got its' roots from the 020 top handle which is to the left in the picture .
Differences are that the 020 Top handle is a side carb ,side exhaust model and the 020 T and Ms 200 T's are top carb bottom exhaust .Plus the 020 TH is all metal and weighs a tad more .
From a design point I would think the 020TH would have the advantage in that the exhaust doesn't have to make a 90 degree bend to get out .
