Vacuum tube brand pls.

Hi, the tubes marked as SPARK. There are writings in internet said it is Shuguang. I do not have Shuguang to compare. I am using JJ, but they are so different. SPARK manufacturer did not mention from whom they order. So, I do not know. Why not provide me email address and I send you picture and you may judge yourself.
