My quest for compatible figures continues, although I may have found the motherload... Irregular miniatures do a wide range of 42mm figures, ranging from flats and toy soldiers to properly detailed figures. It includes a selection of modern milita types, riot police, Vietnam war stuff and lots of WW2 bits. I decided to take a punt on couple of figures after Ian at Irregular said that the figures are 40mm from the top of the head to the bottom of the feet. A quick measure of the HLBS figures showed them to be 39mm by the same method.
The milita range includes a wide variety of head and weapon options, as well as figures im civilian and military clobber, so has lots of potential. I started by ordering a standing and a kneeling civilian, with an ak47 and a DP lmg, as well as a seated military driver, all with random civilian heads
So far so good. The figures are fairly free of flash and cleanly sculpted. The HLBS figures are more detailed, but the irregular figures are quite acceptable! Weapon wise, they match up well with HLBS and the chunkier TAG pieces. The next phphotos are size comparisons with both kneeling and standing HLBS figures. As you can see, the Irregular figures are slightly taller and a little thinner, but I think they should match really well once they are all painted up and based. The chap in the centre of the last photo is from the Irregular late renaissance range, and will be going on a plinth as a statue to some long dead hero.
The last thing I picked up is a 100mm WW2 Soviet artillery piece I picked up from the 'very useful guns' range. The model is pretty big, and although not massively detailed it should really look the part painted up. In many ways, the lack of fine detail (winding handles etc) should make the model more robust.
