Hello Everyone
Some more parts arrived today from Singapore.

The nose retract and header are now in my hot little hands but the OS has not arrived from Finland yet.
I got a set of MK mechanical mains from my father-in-law that he had in a SupraStar (I think) about 15 years ago. They are in pretty good condition and include the Kavan wheels that were on the SupraStar when it went in. The brand new nose unit has probably not changed in design over that time as it matches the plans and is even the same green colour!
I had to lay the parts over the plan to see how they would fit.
