Hi 31, thanks for the comment.
its what i thought too. I used to have 11 pcs of these bullhead.
Had polished some without revealing any base metal.
Had also hand sanding one case (to rid some dent) and has not seen any base metal too.
was a little confuse on the "base metal" stated at the back case.
Bezel look black painted or gold plate on some model.
Was wondering if thr base metal was referring to the bezel instead.
Thanks again for clearing my long time doubts.

Here is V's case and pushers after polishing. I hand polish each pusher by hand and use water proofing grease on the "O" rings to ensure a smooth action. The springs are also cleaned and you will notice on the radico how dirty they were. Its been asked on many different occasions and in other Citizen threads as well as this one on what alloy these cases are made out of. I didnt have any here at the shop to comment but after having these 2 i can add my 2 cents. I can say that the octagon are all stainless for sure and its signed on the case back. The non octagon cases, at least these 2 here being restored are solid nickel. I louped the spring bar holes to make sure they are not brass with chrome plating. These 2 are solid nickel. As far as whats refered to the base metal top on the case back, in my opinion it appears Citizen is refering to the bezels. Which are very soft metal and appears to be either nickel, stainless steel or aluminum. There are alot of these Bull Heads around and V has sent me his NOS Bull Head to compare. I have 3 Bulls here now and i'm planning to weigh the cases complete and see if there is a difference as far as metal content. These 2 older Bulls feel heavier compared to the NOS repo. I will post the weight results in a couple days. Stay Tuned, 31
