MELGAR it's your train, so you have to answer that question for yourself. The 773 is a unique beast. It's neither a toy train nor a detailed scale model, and at the same time it's a little of both. The best examples run as well as some trains that were marketed as scale models. You could fill in that divot and add a bunch of detail parts from the 700E. Weather it to complete the picture. Or you could put it in front of a 773T tender and an operating cattle car, and run it on O31 tubular track, enjoying the puffing smoke and nostalgic smell of ozone. Both approaches are equally valid.
The indentation doesn't bother me personally because I think of it as a toy train, hands down the best-running postwar steam loco. I guess I'm not a scale modeler. I just wish it were a little smaller, so that it looked better with traditional rolling stock and Plasticville buildings!
