Hi Don !
As has been rightly mentioned it is indeed a Wimmer 
HWN was very early on a supplier to many chain stores etc and this little fellow is most likely one of those shipped over in big numbers to the US in the post war prosperity period of the 50's to 60's , hence the wolf in plain clothing look ...
You can also find him with the tender in proud HWN livery
Going by my experience there are far more of these cheap and cheerful Wimmer sets in the States than in Europe! ( because that's where the money was after the war ) It was a real boon to the toy-makers of the time, and they took full advantage of the American presence in Germany , ( Hence the U.S. Zone ), establishing profitable trade to help Germany advance from the terrible destruction and poverty following the defeat of the war . Japan also had a similar such lifeline after WWII ( and even WWI )
Some new ones coming to me ...
A trio of O gauge Karl Bub Baggage wagons 2 in dark brown and one in the lighter variation ...
and probably 2 out of this collection of Bub/Bing that has been offered to me all below are 1 Gauge , ... not sure which ones yet ( lol ) what would YOU choose.. I am being drawn to the two extreme right front and back ones , although the passenger coach is missing the buffers ?
Decisions decisions ....
