Collecting grants of arms

So among my other activities, I collect medieval and Renaissance grants of arms. These are almost entirely English — which is reasonable, since the English College of Arms is one of the few that were active then and still active now.

Looking them over, I have 13 grants from the 15th Century, 26 grants from the 16th Century, and 6 grants from the early 17th Century. (I’m not interested in anything later than that.) Plus four of unknown date. Enough for some stylistic analysis, heh heh heh.
