For some reason this original post did not reach me - Ive only seen replies to
it. Anyway, here is my contribution.
There are pictures of Neville with one of his cowls fitted to an anonymous
tri-gear
with his own engine mount on the Europa Club website at:
http://www.theeuropaclub.org/building/cowl-and-cooling/neville-eyers-revised-cowl
NB I note that the webmaster will need to amend the text of that page in the the
light of Nevilles untimely death, not to mention getting the spelling of his
name right - but he has been rather busy getting new content management tools
and hosting arrangements in place recently.
I have an XS kit and am installing a Rotax 912S with a Woodcomp high-twist
variable-pitch
prop. From my conversations with Neville, it sounds as though I am
the only one fitting his cowl with a Woodcompp prop. I am using the standard
Europa
factory mount and firewall (although I am having trouble getting that to
fit - it looks as though it would be much easier if I could get one of Graham
Singletons composite firewalls - anyone want to take over manufacture of them?).
I persuaded Neville to cut out & fold for me the horizontal baffles that
separate
the upper & lower parts of the cowl, and also to supply new side pieces for
the duct underneath the engine that houses the radiators. (The standard factory
items could have been extended to fit his cowl, but I felt it was nicer to
have one-piece duct sides.) The aft part of the baffle I designed and made
myself
following instructions from Neville, as he only had templates for that to
suit his own engine mount.
Here are some links to pictures of the various relevant items.

I had a phone call recently from Jag Chaggar. He says he has acquired the moulds
for Nevilles cowl and wondered if I had any idea how many layers of layup were
needed on them. I think he has a 914 installation, on an airframe imported
---From USA, but Im not sure if he is on this forum.
LAA mod 13452 refers to G-RICS which has an Airmaster prop and a 912S. I think
it is using the standard Europa factory engine mount. It appears to be a
conventional
taildragger.
Hope some of the above is of use/interest.
in friendship
