The obvious downside is they are Foundry and will therefore cost an arm and a leg, but..... there are packs of bobbies on penny-farthings and horseback, a pack in capes and one armed including a couple of Martini-Henrys.
Even though there are only 5 foot figures and 3 mounted per pack they are still highly desirable
As ever, apologies if this has already been posted somewhere.
