Ive recently finished these resin pieces by a maker called Baueda. They are very nicely detailed and of great casting quality. I do have some more fortification type pieces in the pipeline, so Ill do some more hopefully soon. These were easy enough to paint, with the sawn off short ends of the logs requiring some detail work. But even that was surprisingly quickly done and adds very nice detail to the pieces.
The models are sold as WW2 pieces, but I think that fortifications like these were in use earlier – at least they are similar enough to Napoleonic fortifications. Ill combine these with some gabions, which are more typical of the period.

They look very nice! That’s a manufacturer I had not heard of before.
