There ought be 6 of them but goodness only knows where number six went to. I checked on the Foundry site to see if they still make them and of course they do.Undoubtedly overtaken in quality by the plastic and metal offerings from the contemporary Perry collection (but with less flash I'm prepared to bet) they retain a certain charm but a horrific price tag. The livery is a made up combination but hopefully not too garish that they cannot hold their in some 14-15th century confrontation.
As usual ebay beckons. They can be found at http://www.ebay.co.uk/itm/282039191446?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2648
