The Foremost range was originally advertised as a separate venture by Peter Gilder, though it was always exclusively available from Hinchliffe Models. When Frank Hinchliffe sold out to Skytrex the Foremost range went too, so whatever the commercial arrangement was with Peter Gilder it must have ended there.
PG did some of his best work for the Foremost range - the British Napoleonics come immediately to mind, as do the horses. That said, i prefer the earlier Hinchliffe ECW to their Foremost peers - the 'Prince Rupert's Charge' cavalry were a late addition to the Foremost range and are a tad chunky for my liking. Nevertheless they retain all the elan of classic Gilder cavalry.
These particular examples were painted as Ireton's Horse by John Tilson, and a splendid job he did too. If you've been paying attention then you'll remember that John took part in the Edgehill episode of Battleground. Something that was not noted in the Battle article i posted earlier was that John used his own Parliamentarian army during the game - sadly this army was stolen a short time later.
Win absolutely nothing if you can identify the classic tome that Ireton's are deployed upon.
