Hugh,
Here is a link to find the installation manual and revisions, latest is
2004.
http://tinyurl.com/ft4r2
This is the link to find SBs on your engine. It is not hard to do.
Easiest way is to search using the serial number of your engine. This
eliminates those that apply only to other engines. Among others, there
is one there about the oil venting which is 912-036.

Sonny,
I had a GSC in-flight adjustable prop on my old Titan Tornado and it
was great. I believe the cost is around $1,400. It is mechanically
adjusted with a vernier control just like that of a constant speed
prop, but without the governor. In my opinion it is better than the IVO
electric adjustable in common use in the USA. If you are interested,
there website is

adjustprops.htm
I don't have one on the Allegro because we want to keep it legal S-LSA.

Thom,
I had not seen the GSC props. They look really good, and the in-flight
adjustable looks simple and elegant. I am not altogether happy with my
Ivo three blade for a couple of reasons: first there is no good
provision for leading edge protection, the stainless steel tape they
recommend does not stay put for long. The prop itself does not appear
very presicely made and I can't get away from the feeling that I would
have a smoother running setup with something else. The adjustment
mechanism is easy and effective, but I would trade that for higher
quality, and I am tempted by the in-flight adjustable feature for all
the reasons we have heard in these pages. There is another good looking
prop that is relatively new. Check out:

Does anyone have experience with this setup?

Jack,
One (main) reason I liked the GSC vs. all the electric operated props is that it
is mechanical and you tell by the number of turns on the knob exactly where
you are in pitch. There is no gauge nor need for one. The electric props, at least
the ones I've seen, have brush wear issues and you cannot tell exactly where
you are in the pitch range.
Also, the prop is very well built and rugged. Mine had the Maple blades (light
weight) with a leading edge insert of some sort of black material that was harder
than all the rocks and stones that hit. With the pusher configuration, the
main gear tends to pick up stones and throw them into the prop. My prop showed
no damage after 6 years and three hundred hours of use. If you prefer, they
can also fit Warp Drive blades to their prop hub.
I know it sounds like I'm selling the GSC but I'm just pilot who has had very good
results with the product.
