It could very well be a VHII bridge, pickups can vary between actual and listed DCR (my HD is listed as 16k on the site but the card that came with it said it was wound to 15.6k). 8.37 is quite close to that of a Mule bridge though, but the Mule is AIV whereas the VHII is AV, so I suggest you let your ears tell you what's good :D
