Info on stitching thread

We know our leathers are Connolly. Has anyone posted information regarding what brand threads were used to stitch everything together? Brand, size spec, color codes of threads Ferrari used on our cars would be appreciated.

Might seem trivial, but I've seen contrast stitching work done where the thread size and color doesn't look correct to my eyes. I prefer to stick with exactly what Ferrari used or something 90% close.

 

Given how hard it is to get this type of info out of Ferrari how about contacting Schedoni? They seem to be approachable and while they don't stitch the interiors I would think they would be able to identify the thread used. Just a thought.

 

Maybe send Henk van Lith an email asking him the question:
