Ambassadeur 2500C (A-A25-00C-0-008-N-R)

A rare example of an officially termed “Black Special” model.
A new smooth spool was observed to be used starting from the Olympic era.
Produced in 1990:

This was the era where ABU adopted the new technology of welding the Foot Pillar to her frame; instead of soldering them like her predecessor.

An example of how technology evolved: This is an early frame where the welding marks were either absent or faint as the initial batch of Foot Pillars were welded to their frames under low current; a slower process.
While the same part number #8722 was used on the Counter Balance Handle for these Black Special Ambassadeur 2500C, this handle was not the same as that used on Ambassadeur 5000C, 5001C and 6000C in the classic years.
