I would love it but no spare money these days. It gives me lots of information if I restore barnfind. I posted on crumpets greenfield javelin that you thought was a prototype. Javellin was known as Kerr's Fauxpaux or another word starting with F. It finished production by 1979 and only ran for 2 years max.
Note for prd. Fibreglass nose cones were made for one year only and I calculate it as 1980 or 1981 as I worked there during the Fibreglass phase which also included the 5XL motor covers. Aluminium castings ended up cheaper than Fibreglass. The cowel for the 8xl was alloy. The 5xl cover resembled the duck tail of a Suzuki motorcycle on purpose.
The 8XL was due for release at the same time as Whitlams dismissal by GG John Kerr. They were going to nickname the 8XL as Kerr's Kerr.
