For the benefit of the Forum here's what I've discovered:
Scan quoted as follows, for sets of screws:
BMD-BMUMCAPRO/MSCRB - £9.00
BMD-BMUMCAPRO/MSCREF- £9.00
BMD-BMUMCAPRO/MSCRPL- £15.00
c/o
scanprovideo@scan.co.ukOr BH (US based bhphotovideo) were the only suppliers I could find with a cursory internet search @ US$15 per set.
Or - I tried another supplier that will remain nameless, but they're the guys we use for almost all of our big kit purchases. They put me on to their service department who wanted £22.29 per set of screws + £25 Spare Part Administration Charge...
Bottom line - they're expensive bolts, be careful with them!
