Terry;
Hi!
Got home, tried my home machine, and.... voila! Pictures!
Really NICE job! I have to echo some above and say that your exhausts are pretty sharp and convincing, and the weathering is pretty good, too. Not too much, and gently applied. The bits of stuck mud look pretty convincing (one of those things I have not yet done well with, I'm afraid...

).
There are a few things you can really easily fix up to make this super, IMO... They are all details and only my suggestions - I think your build is primo as it stands, but there are always some tweaks a guy can do!
1) That turret antennae. Ugh! It must be about 2 inch in diam! Really looks bad when you have that much nicer (and more to-scale) "Sternantenna" right near by! Just cut that pipe off and add some stretched sprue about the same diam as your star-post, and you'll be off to the races. Scale it to typical 2m length. That, and paint it black. (There were some also painted in the standard equipment dark green...). The real thing was tapered... easy to do when you stretch sprue. It will naturally have tapered portions when you heat and strtch it. Just pull it out and select and clip the section you like!
2) Wire that turret antenna at its base with a nice thick black cable looping down to the rear of your radio. German vehicle antennae had these typical, visible cable connections which coupled into either a gang-box adjacent to the radios (and coupled to same by cables) or directly into the radio. In your rig, you have nicely wired the command-net sternantenna - your turret aerial needs something too!
3) You supplied some really nice head-phones. Maybe a mic would be appropriate? Both the 'phones and the mic plugged into the front panel of the standard radios- usually jacks side x side. (IF 2 radios are visible, both would have a mic... )
4) I really think you did a super low-scale wear n chipping job almost everywhere. Right up to when I looked into the turret ring in front of the gun shield... looks conspicuously clean and sterile compared to almost everywhere else. Get a little "funk" in there for a balanced dirtiness!
5) Kinda last but weirdly stands out... specially as you showed a close-up view of it...! The rear convoy light. It needs to have the lenses colored in, and maybe dirty the thing up to fit in with the rest of your great build. I THINK the little lights were all one color - either green or blue (and whichever you use, DARK, as in unlit darkened lamps).
Again, these are details... you have a great build here, and I find it very inspirational! Thank You for sharing it!
