So after a couple of days here is an apdate on what has been done so far. I added a few details and started on the weathering. I decided to add only remnants of whitewash, because on most of the pictures from Battle Of The Bulge Half-Tracks are without a whitewash, or the whitewash is only limited. I didnt find any pictures of a M21 from that period so the serial number is fictious one.

Hi Naseby, well this is exactly what I need, some US halftrack inspiration as I'm on Number 1 of 5 I have to build. I have started on the M4 and am doing it in a white wash scheme also. Love the black dog set and will order asap ( for the M16 which is up next )
Following intently....
Cheers Les

Thanks for the comment Les, Blackdog is the way to go if You want to add some gear. But I also used some from Tamiya. Heres a lttle update. The wheels and tracks are in place and some light weathering was also applied. I will add more stuff and put on some additional mud.

The M21 is 95% finished. There are a few small things which need to be done, but overall its done. Now I will concentrate on the figurines and maybe a small base to accommodate the whole thing.

Looks good! What jumps out at me is how nice your stowage has been painted. Great stuff! Can I suggest 3 things to tweak? 1) The two .50cal ammo boxes atop the fiber mortar tubes -- very heavy (damaging the tubes) and very precarious -- fall-- break GI's big toe -- big ouch! Why not store them in that slot below the radio?

2) the open receiver of the .50cal MG -- the rod that sticks out of the right edge is inaccurate. It was an attempt by DML to replicate the charging handle which was attached to the receiver's right wall. Google pics of a .50cal MG and you'll see what I mean. You need to snip that off and re-create a better charging handle.

3) Don't forget to add the headlight lenses.

Hope these help!

Hello Roy. Thanks for the comments. I will fix the .50 cal charging handle, thanks for the advice. But I will leave the ammo boxes, these are not only used for ammo but for all sort of stuff,even the empty ones were kept just in case they might be needed. There is additional box directly beneath the .50 cal, behind one of the seats, where the gunner could reach it. The lenses will be covered in mud. Im planing on adding some scenic snow and more mud as the last part of the weathering process.

impress by your work!

Thanks Richard
