Sorry for the delay in answering, Went to CNAM today, firstly the Nipper frame is still there, and under cover, in the ‘new’ cockpit display area.
Secondly I asked the friendly staff about it’s ID, none of the two people I spoke with had any idea ! It was donated some time ago by a former lecturer with KLM Engineering upon his retirement.
Could not get close enough to gleen any info as the new poly tunnel building is not open yet, just pocked my camera lens through a gap (with permission).
Aparently there is talk of making a wing and other parts, but that is way off.
Hope this helps a little. Keith.
