a genealogist's sketchbook

I am researching the Mackworth family of Rutland and Shropshire, who descend from Thomas Mackworth of Derby, who with his brother John (a canon of Lincoln cathedral) was granted arms privately by John Touchet, lord Audley, in 1404. I was curious about the phenomenon of early private grants of arms until I found the excellent set of examples put together by Sebastian Nelson (now an archivist working for the State of California at Sacramento) on two pages, one for private grants of the fourteenth century, and another for early heralds’ grants (but with an introduction discussing private grants).

The original of the Mackworth grant of 1404 was in the possession of the Mackworth baronets of Normanton (Rutland) at the time of the Visitation of Rutland of 1681-82. It is published with that visitation, as edited by W. Harry Rylands and W. Bruce Bannerman in Publications of the Harleian Society, vol. 73 (1921), pp. 12-13. I give the text of the grant here:

Taken from the original in the custody of Sr Tho: Mackworth of Normanton in Com: Rutland Bart. 30 July 1681. By me Gregory King Rouge Dragon.

This edition draws from Gregory King’s text in the Visitation notebook, CoA MS K. 1, p. 249; with noted variants in what I assume is a copy of the visitation, BL MS Harley 1410, fo. 43. I have expanded some of the abbreviations left in the printed edition; but my question marks are for things as printed by the editor which I don’t understand and perhaps he didn’t either, or Gregory King didn’t. The engravings above, of the escochun dessoubs paintes and the grantor’s seal, were presumably done from Gregory King’s sketches.

Now, is there any chance that this original grant, as shown by the Mackworths of Normanton to the herald in 1681, survives and has been described, transcribed, or even photographed elsewhere?

I suppose I could write to the current baronet to find out.
