Hi Kevin,
Info is a little sketchy...
00376G Is not listed in the surviving documentation.
The below are listed among a larger batch with the following heading.
CANADIAN REFURBISHMENT CONTRACT W8466-7-EHB17/01 DATED 26-11-87
ALL RECORDED IN C3A1 FILE ON LINED PAPER CONTRACT COMPLETED AND ALL RETURNED 31-12-1989
00055G
00111G
00268G
00478G
That's all we have unfortunately, I do hope that's a help.
