First things first: thank you very much. The figures arrived this morning and they are just what I wanted and have solved nearly all my problems.
For everyone’s information:
 The Peter Pig foot are an almost exact size match for the Roundway foot figures I’m using to refresh my War of the Roses army. They also match the Warrior ACW figures I’m using. In both instances it looks like I can use the Peter Pig ranges to add a touch of variety. Roundway & Warrior sell single pose packs.
 The Peter Pig mounted knights are a close match to the Roundway armoured knights I’m using but the horses are a little smaller. I could probably get away with mixing them but I’ll have to be selective about poses etc.
Finally, I have put the 4-5 painted samples you sent in the paint stripper but only because I want to double check the above comparisons with a few painted examples. As to any “Muppet painting” I was pleasantly surprised: your comments had led me to expect something far worse.
