Gents,
I noticed this manual for sale:
https://www.ebay.co.uk/itm/146696389...=&toolid=10050
If you are unfamiliar with it, the GM 6062 was an improved version of the GM 6004 used in the GM-powered Valentine tanks. I do not know the actual application for the 6062 ( maybe late Valentines or Archers).
These books also include the 6004 parts list which includes all of the part changes during production.
I personally feel that it is a very valuable book for someone contemplating a GM-powered Valentine or Archer restoration.
The listing only has one image and a short description. I certainly have no idea if the book is complete. The listing shows that the seller only wants to ship within the UK.
The attached images are from my copy of the book in case you are interested in the contents.
