Dave, Mountfords figures are a little better than 'toy soldiers' but not as detailed as we would normally expect as models. The guns are excellent, I've made a few before as vignettes with their crews and they look very effective. If you can ignore the scale difference I'd rather use their 25pdr than Tamiya's !!!.
Dave Love is a master sculptor, and the artillery is his main interest.
The 3.7" that I made was available as a metal kit, but has now been remastered as a mix of resin & metal, slightly cheaper and a heck of a lot lighter. I bought it through Matthew Tarrant at
