About 10 years ago I tripped over approx 1200 original Phil Irving engineering drawings from what looks like the F5000 or F1 Holden engine days. Included in this lot was a stack of F5000 chassis histories with who drove what chassis where and what was done/repaired etc on the cars. Just about all of the engineering drawings are signed. Some are real big(desk size) and some are smaller (A4). I have no idea what they are worth. Hopefully there's an expert out there that can tell me??!!

Yes mate, we have an ebay store called Kingswoodcountry. Thanks.
