Here is the latest and almost last update...
Here is the construction, sans wheels, tools and paint. Fit was so-so as mentioned. Couple small parts went flying and not included.
Tracks were a major pain; do NOT use any type of liquid cement on these types, they melt COMPLETELY. I had to anneal the tracks as best I could with acrylic-based glue. Spare tracks and muffler painted, tools painted on sprues.
Painting - My AB booth is in an attached unheated garage. After painting, I was cleaning up and forgot to bring in the model... overnight at near freezing temperatures had an effect in the painting, you can see some paint dimpling and orange-peel like effect. Normally, I would re-paint, but lack of time prevents that course of events. Will have to touch up if possible.
Back assembly, with tools, spare track, etc. Will touch up after installation.
After paint touch-ups of the tools, spare track and muffler.
Decal on.. had to coerce it with some microsol. Tracks on...very tight, about 6 wheels broke off... some are distorted now..ugh...
Pinwash with burnt umber, some slight dusting. Tracks dry-brushed steel after burnt umber wash.
Letting everything sit and dry for a bit. Will end up this afternoon with some pastels weathering, maybe a touch of a sludge wash, not sure yet...
