[Mgs] gold sealed engine

[Paul Hunt]

It's 'Gold Seal', and is a factory reconditioned replacement engine, painted 
gold instead of red or black.  My understanding is this was a complete 
engine that had been, for whatever reason, stripped, every component checked 
for damage and measured for tolerance, and rebuilt using new components 
where required.  As such Gold Seal engines were said to be better than 
originals, for with originals parts from the component manufacturers were 
fitted as-is without being checked or measured and hence rogue components 
could get through and cause problems later on.  There were also Silver Seal 
engines, which I think were 'short' engines i.e. incomplete, no connection I 
know of with an American company of the same name.  Gold Seal engines have 
their own series of engine number prefixes beginning 48G and latterly BHM in 
place of the 18G, 18Gx and 18V of the originals.  The other prefix and 
suffix letters were as for the originals.  See 
http://www.mgb-stuff.org.uk/wn_engineframe.htm and click on 'Gold Seal 
Engines' for how the Gold Seal prefixes relate to the originals.
