Just checked mine, yes they are, and diagrams, drawings, specifications, contract and manufacturing numbers etc.
I have volume 1 only, bit pricey, check Amazon see if any used, they are about £40.00 New, but worth every penny!!!
Had a quick check on the numbers you provided.
Quick search says
Closest engine number to yours is 8087, on a Vickers Armstrong MK 11 Dragon!
Your hull number comes up as between T13678 - 14677, Universal Carrier MK1, contract number T7810 made by Sentinel Wagons, 1000 of that contract made!!
That's what those numbers show up mate!
