A while back, I posted pictures of how I modified the Armco barrier which comes with the Tamiya pit set.  I gave it a coat of primer, so now all I have to do is paint it up (Red&White I think?) with some appropriate weathering and it should make a nice “prop” for photographing the 1/20 driver figures. I placed it on a suitable base to take some test shots and see how it looked with figures of the same scale, and I think it looks the part.
