Thanks to several other members of the RC community this little nugget is winging its way to me at the moment.
It looks to be the same undertray style used by Umberto Pernice in Romsey in 1987, and to me appears to be the same shape as the Coyote bodyshell. Whether that doubles over to the Pro10 shell i am not too sure. I will check upon arrival.
Either way, it is a great find

If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.
So i checked the undertray with my Coyote bodyshell.... it remains a bit of a mystery really. It does fit inside the Coyote shell (width) but is longer at the rear. I think it may be designed for both the Coyote and the Pro10 and you just have to trim the rear end accordingly. It is certainly listed as a Pro10 optional tuning part based on the part number.
I have now arranged for Penguin to receive it and reproduce it, so everybody will get the benefit of it as required.
