Picked up by me on eBay the other day. Most of the lots have figures against them in the brochure with a 1958 BRM P25 with chassis number 25/8 being shown as sold for £85,000. A BRM H16 engine sold for £5,500.
A 1954 BRM P30 1.5 litre V16 chassis number 2/01 sold for £160,000 and chassis 2/02 sold for £100,000.
Fascinating to look through, I do have a few pictures that I will post when I can
