Horses were as per the Cowboy set but with minor changes now looked at below The same horse was used with the first version Foreign Legion.
Removal of head-dress leads to Roman civilian patrician (blue and white figure) wandering down to the forum, while removal of baby and papoose gives a variation of the female pose. The other is a standard - Terry Wise school - wire spear, also with head-dress removed.
Fight to the death; "It's him or us!"
"Heap big'um monster" as Little Plum might have said in The Beano!
Montaplex/Hobbyplast sets, wagon-raid on the left, straight duke'ing it out with twice the figure ration on the right. These are really quite poor figures, even by Mantaplex's standards! Both actually badged to Hobbyplast.
Size comparison between Airfix and various Walter Merten examples, including a Hong Kong piracy on the far left of the line-up, the Airfix is fine with the commoner Merten's, a little bigger, but that is mostly base, but he's noticeably larger than the two on the right who are from another set. The HK figure seems to be a melding of the two poses to his right, but my catalogue in in storage and it may be a stand alone pose in its own right?
While a solution was sort, the blurb was allowed to mention the Cowboys as a possible, because the catalogue artwork had a tighter time-pressure than the set itself. That blurb then became the default blurb in the catalogue/s every year, while the conversation about what to do probably covered a set of foot cavalry being developed and/or using the Union Infantry (or Cowboys) and/or other scenarios that ended with the compromise of including the Cavalry, and hoping a few settlers could populate the walkways?
Marx by Marksmen via Rado Industries (Ri-Toys), despite being among the smaller of the figures from Marx, these still amnage to dwarf the Airfix offering, but not by much and a bit of paint and scenery could have them working well together.
