OK, the set shows GS1 in Tradition's catalog, in the toy soldier range ("Toy style model soldiers for collectors"). It consisted of 8 figures, including Tilly, the Bürgermeister, and six soldiers.
Of the soldiers, 2 wore lobster helmets and cuirasses over buff coats; 3 are musketeers, one with a helmet (a casquet, I think it was called) one with a cocked hat with plume, and the third with a plain hat; and the last looks like an officer, with a cuirass over a buff coat, broad-brimmed hat with plume, and a Pallasch or long, straight sword.
I'm not sure if Tradition still makes this set, though, I think I saw elsewhere that it was discontinued. Recently, though, they've revived some sets that show as discontinued in this catalog. For example, the Steadfast Toy Soldier set that Jeff just painted in another thread, was discontinued when this was printed. So were the Victorian Life figures; I think they've recently been re-released.
I page through the catalog, I also see 3 figures specifically from the English Civil War:
No. 511, Trooper of Parliamentary Horse
No. 510, Officer of Royalist Horse
No. 512, Musketeer of Trained Bands.
Figure 512 looks identical to one of the figures from the Meistertrunk set, BTW.
I haven't gone over to Tradition's website yet, to look for any of these, but it's worth a look.
Prost!
