QR554 is on the verge of late HQ, early HJ. QR740 is early HX. All I can tell you is they are not from a Statesman and all will be trimatic/4speed blocks. _______________________________________________________ If we all had the same (goo

It still doesnt explain a jump of 180,000 numbers. James --------------------------------------------------

Then I remembered it being said (Here I think)that if there was a problem with a block it was laid aside and then fixed at a later date. This woul
