Looking good! Will be watching your progress with interest. Soft spot for the Auster, had my first ever flight in one out of Bristol (Lulsgate) A/P back in 1960('twas G-AHSO, see it's not airworthy now.) Must try and catch up with it one day.
You seem to have plenty of parts available but I have a few 'NOS' parts if you're looking for anything specific? Do you fly anything at the moment?
