That would make sense to me since the change occured
just prior to the start of 'B' production, but I've no way of
confirming this ... IOW, seems more likely that they would
have used the pulley from the, soon to be introduced, 18G
engine than to produce a part that was only used for the
last 588 16GC engines ... I've seen the factory "Parts Lists"
advertised ... perhaps the change is documented there ...
anyone have the MGA 1600 Parts List? ... does it cover
the MkII changes?  (Interesting to note that the VB Part No
for the 'A' pulley is the same as thier 'B' part number for
for engines up to 18GUH5571)

Several other notable changes occured that could lead one
to believe that bits from the, soon to be introduced, 18G
3-main 'B' engine were being fitted to the 16GC engines ...
though they could be just normal production changes that
carried over to the 'B' ... should prove interesting to check
these against the 'A' parts list.

Sept '61 commencing with engine 3708 a "[l]ighter flywheel
was introduced" ... Oct '61 the "[g]earbox first motion shaft
with involute splines formed by rolling, giving stronger spline
section at reduced cost; clutch driven plate modified to suit.".

Agreed ... the point I was trying to make was that the TRF 'B'
Part No 12H 775 crossed with the Brown & Gammons 'A' Part
No 12H 775.

It would seem that once the change occurred the old part
number was superceded by the new ... IOW, all subsequent
requests for an oil thrower were filled with the new part ...
make sense?

Keep me informed as to which vendors ya still need and I

Wayne Kube has already forwarded this to you ... let me know
if ya didn't get it.
