After a number of false starts eventually I got a combination of the Hat sailors that looked something like they were hauling a gun and limber. There are a couple of oddments mixed in, but I leave that for those interested to identify. The limber is the old RHA limber from Airfix with "shoes" added to spread the load on sand. At the moment I'm still using the Strelets guns with a single trail, but an older split trailed version was used in Egypt.
A close up version
and the idea came from the Perry's version in 28mm.
