I've been pretty happy the last few weeks because I took a massive step towards to achieving my Grail, a mint, unpolished (case)6138-0040 "Bullhead". Some of you, who like me scrounge around for 6138 or other vintage Seiko parts on ebay might have found the seller with a few "sample" NOS cases, I couldn't believe my luck. So I acquired a couple of bullhead cases as well as a 0011 ufo and 0030 kakume from the seller as well.
On receiving the cases, I realised the best bullhead I have (I have many ) is not too far off the mark in regards to unaltered edge lines on the case. Everyone is different, but for me, when assessing a vintage piece the order of importance is 1) the case condition eg original edges not polished.
So I won't use the new bullhead case until either this bullhead needs a service or a NOS 5Sport Speedtimer dial shows up.
