You have to be more specific Steve. The leenkamer documents have been renumbered several times. There is an old LRK 314 (LRK = Leen- en Register Kamer) which became AGH 211 (AGH = Archief Graven van Holland) and which then became inv.nr 271 in 3.01.52 (the current number). But this is a copy which is in Haarlem (NHA).
And the current 314 in toegang 3.01.52 is a copy of AGH 303 (LRK 18) which should be in Middelburg, Zeeland...
Very specialistic job, archivist, so I hope I didn't muddled it even more....
