To the right a Battleground set, these were made in Stockport in the UK, by Power Play/Mainstream Products, but seem to have been mostly sold in the US, probably so's not to get into a major war with Bellona. Some sets are similar to Bellona, others however, are quite unique. There seem to have been at least 18 in the rage of which I now know of 13.
Going back to the bridges, you can see two treatments, either cutting them out with the culvert filled and painting it a dark colour, which leaves a little strength in a flimsy moulding (bough-in in a mixed lot of tat), or as I began to do (20+ years ago!), base it and cut out the culvert arches ready to paint 'water', the base giving it a strength that will help it survive a hundred war-games.
Here we see more examples of mine and another's work's to strengthen/enhance them for war-gaming, A) shows the basing of the set to the left, with two different approaches to cutting it out, the other guy (far left) will get cracks forming inward from the acute angles he's cut at the back of the position, cutting straight, on the flat area of 'waste' sheet prevents that, basing gives stability. B) Filling the gaps in a tightly-trimmed piece and starting to landscape with door-mat beatings.
C) shows a plaster-cast I've taken from the shell-scrape to the right, you can make quite a few castings before the vac-form starts to suffer damage. D) Is two treatments of a shell scrape to show in the upper example; a 'usable' (by troops) 'shell-scrape', in the lower one; a mud-filled 'shell-hole'. Humm...not much difference between shell-hole and hell-hole, huh?
The wall's (top left); Showing the way I created the one in the middle, first I cut the ends off two short sections (I couldn't wait for Tangley or Concord Models to get the long lengths in!) and glued them together before highlighting the 'gaps' in the dry-stone with matt black (1), then painted the stones in one-at-a-time with different shades of grey, keeping the darker 'Atlantic Grey' as the predominant shade (2) and finally dry-brushed in pale gray before flocking the base with saw-dust 'scatter'. Twenty-plus years and I've got one length finished!! Ah...you either collect, or war-game, or model, if you try to do all three you're bound to fail at at-least two of them!
I've also shown made and unmade corner pieces, note there are at least four colours/shades of plastic here, if someone tells you otherwise, send them here!
Again Efka produced a very similar sheet (I recon - if treated the same as mine they'd be hard to tell apart), but with angled sections at about 50% and a strange corner piece that meant you couldn't produce a usable enclosure (or 'run') from even two sheets?
The other tent is a bit of a dead-loss, can't get it to look realistic enough for my taste and if I re-did it now, I'd replace my rather weird attempt at a rolled up door with something bunched in ties, from tissue-paper. Efka went with a slightly more plausible medieval looking thing, but binned the Bell-tents for two horrendous 'coconut-shies' and had a similar number of blobby Pup-tents.
