Looking good. Love the drums as well, good to see the Earl's coat of arms there as well.
Wigster is quite right as Manchester's Regiment (which I believe was later merged with a few others to form Fairfax's Foote of the New Model) were Puritan. Interestingly though not all Puritans were the Godly saints they made out to be. Cromwell (okay technically he wasn't a Puritan)used to like dancing and pulling practical jokes. There is an old legend that he had an ink fight when signing the King's death warrant although I think the story has largely been discredited.
Companies would be a mixture of musketeers and pikemen (usually about a third pikemen, two thirds musketeers. Royalists tended to have more pikes due to shortages of muskets at the start of the war, although some Roundheads had shortages as well. By the end of the wars though you would see more musketeers) and normally between six and ten companies although as time went on they would just merge them. Interestingly many soldiers would probably say they belonged to a particular company under Captain [insert name of Captain] rather than to the regiment.
To be fair with the beer/bear point, most people here in Norfolk pronounce it bear...
Well this got off topic fast!
