Another little point of interest while I remember. The Ickx models also appear to have a higher grade movement. While the Sears/Leonidas ones I've had seem to come with the single jewel 8420, both the Ickx versions I've serviced had 17 jewel 8420s.
On another note, the split stems simply do not exist to buy, I ended up having to make one from scratch!
Great piece. Just agreed to buy a black faced Ickx with a steel case. Will post pictures when it arrives.
