They did make small Marx versions of the plastic frontier and military stuff that might be usful as individuals, but not so much useful as a full set with log cabins, etc. The fences are ok. The military tents might be used by drovers or for some shade away from the house.
Ranch items could be selected from other farm and industry offerings too (Plastiville). A more modern ranch home might be painted as old if that's the goal vs a "pretty" one.
Slightly oversized maybe, but some of the cowboys, horses and wagons I've posted are just Dollar Store (not D.Tree) toy packs I painted. I think they used to be a Marx cowboy set too. Just ask if you want a comparison photo of $1 cowboys and wagons near a train car/truck or ruler, etc.
Look at the Bay for lazer cut western building kits for the old western town buildings. (and search "old west" "desert" threads here, maybe three years back there was a few... closer to 6-7 years back there were a few very deserty layouts, but the one member I'm thinking of most was a real polecat who complained about everything and would get super rude and insulting at the drop of a hat...or the wearing of one.. or your hair color in contrast to the hat might p*** him off.. Simply being too friendly to him got a few folks "attacked", lol.
I think he might have deleted everything when he finally moved on. (after quiting and rejoining a few times... He couldn't hide that attitude with a new name)
(easy cardstock or wood kits, $10-40 average, some are 99% ready printed/painted... hot glue and sharpie marker or paint for scores and folds where ink breaks up some. Some prints can be glued to wood or hardboard or posterboard for more strength, but they look better than it sounds with just cardstock though.
The traditional O-ish army men/cowboys are actually 3+ sizes, the larger are obviously oversized at 2"+, but the two smaller ones dont stick out as giants with a little "forced perception" and well matched items close by, imo.
(forced perception is mixing scales to a visual advantage; overscale up close, normal scale midway, and smaller scale scenery at the rear of a scene, to imitate depth of vision).
Cows and horses really aren't hard to find at all. Model boat props make decent windmill blades; kinda fat blades, but passable for a small generator or later well pump imo. The towers are a nice fireplace matchstick or plastistrut project, but I know a few are premade too.
Folks don't mind the asking for photos and scenes. They tend to want to share (though lately dragging photos out of folk is like pulling teeth. For some reason folks seem to avoid it at all costs all of a sudden, and don't insert them in text when they do (the thumbnail viewer doesn't always work for everyone and full sized is also actually seen vs accidently missed or skipped and forgotten.)
It just makes for better referencing if it's in one spot vs a few spots. Reviving a thread you started to bring it back into the light isn't the same as bumping an ad (huge no-no). The alternative is half a dozen threads with the same requests and that make reference hunts needles in haystacks. (cripes,.folks complain when different folks start similar threads, the same person doing similar threads, it gets very confusing; bump your old thread after a day or two/week to rekindle attention)
