Taz,
I believe this is called "synchronicity". Earlier this week I was at a local Air Museum which has a fair sized library and a copy of Klaeyle's and Osche's book. Wonderful. This is where I saw the photographs of S254 I described earler in the thread.
I was impressed enough that the following day I ordered a copy online and it should be on its way from England as this is written. The down side is the French language is not my strongest suit. The upside is I have a niece who has studied French for five years and is quite good. I already told her I have a project for her.
