When I grow up I want to be Compo- minus the feret

The 99 78xx numbering was from the time period over the second world war- 1938 till 1946 from memory. Not many OBB loks had coal bunkers- 298.56, 298.106, some of the SKGLB loks and Murtalbahn but that is all to my limited knowledge. The bunkers on the side tanks seemed to be fairly random and as the time suited. most seemed to have the slopey ones pictured in this picture. I think LBG produced both varieties.
