Blacksmith forge in 1600's would have looked how???

Hi I was wondering if anyone had done any research or would know where to
look for information on how forges were built clayed etc in the 1600's i
have reproduced a set of period bellows and am in need of plans and or
information about forge construction in that era also it needs to be
portable and simple wood metal lines etc would be doable hope this helps
describe what I'm looking for.
TIA, Vaughan
