Ted, there were different grades of Miroku sidelocks. Some, for example, didn't have ejectors. (One of my hunting partners owned one of those.) BSS sidelocks were all one grade, the only difference being game scene engraving on a few vs scroll on most of the 12's and all the 20's. But I agree there aren't enough Miroku sidelocks out there to make a really accurate comparison. But when you do find a Miroku-marked sidelock that has similar engraving coverage, features etc to a BSS, you'll also usually find a significant difference in price.
