Mel, here are some more pictures.I tried to add some aquarium charcoal to the tender load. Painted the whole load with white glue then rolled it in the charcoal. I wasn't thrilled by the result so I cleaned off what had stuck and washed the glue off before it could set so I wouldn't have that Elmer's shine on the tender load. I may experiment with an old tender I have, may be the bed of charcoal I was rolling it in wasn't deep enough or there wasn't enough room to displace the charcoal so that there was enough contact with the existing tender load.
I also contemplated add smoke lifters since many of the Mohawks sported them at different times throughout their time on the line. Couldn't find any available, was thinking about fabricating some but the author of the article I used thought the lifters didn't do anything for the looks and lines of the engine. After studying pictures I agreed with that assessment.
