I mined 11 blocks yesterday with 10 Dell R620 servers (2 x Intel E5-2697 v2's each), can you tell which ones are mine?  

As a smaller subset to reduce copy/paste size in the message, yours are among this set for the 12800-13000 blocks:

12803     "nOffset" : "d5a1ebe253189505c4e30fa821352496ac07a2d8c390e09ec02fb4a886603ff3",
12814     "nOffset" : "af26f5e1ef40f66e4c22daf3b5401c5d3061f9644b9063f79bdd296ba1cbc771",
12894     "nOffset" : "a93eeb35b6f16230890569786c8d54d81af197f4058870ca730581ec4121ec5b",
12927     "nOffset" : "f5c103d9133388bacc0cbf0716ff22490879f1b93882dfc1c765f4da65ea723d",
12961     "nOffset" : "7bd1fef8febc067f30bb3ea09619f402f84b7cfe6d76bec97a0335bd6aacc009",
12963     "nOffset" : "5383a9ad7313f65a6981e9e80d6a874e90dad31f35044c224423e8dc77375e39",
12968     "nOffset" : "2ebe04d88d659ee0994aa61c15892e2d348d56aed43cf57d127cf5e5afb88b21",
12969     "nOffset" : "27f8f4155a2f33b82c96401330a44eb60e3ef46af5a59235d799159c87b26a33",

I haven't actually computed the likely primorial for each of these - just going by offset size, so it's possible someone else's miner is mixed in there.

These are probably Firkraag's, using a larger primorial but still in the jh framework:

12805     "nOffset" : "000001bdfbfccd8ef2d06d65b78b3073264c25ce8a7631e8288641262451924d",

and these are n*2310+97 miners - all default jh variants, including mine:

12808     "nOffset" : "000000000000000000000000000000000000000000000000000000000c934a4d",
