I suggest that you post in the classified section of this site, and also in the classified ads section of www.rrbew.co.uk.
For each item please specify:
TSD publication number.
Whether original issue or reprint. (If original look for chassis number of vehicle it originally came with. This would be a hand written note, usually on the inside cover or very early pages.)
Whether original (fold-out) wiring diagram is included.
Suggest that you leave yourself open for best offer during a specified time period.
With more details, per above, I might be interested in some of these handbooks.
