VMs: Does the negative rotograph still exist...?

[Nick Pelling <incoming@xxxxxxxxxxxxxxxxx>]

Hi everyone,

Can anyone tell me if the negative rotoscope of the VMS (that was used by 
researchers early last century for making tracings of the lettering, etc) 
still exists anywhere?

I'm trying to resolve a apparent inconsistencies between the CopyFlo and 
the VMS itself: I've looked at the positive (paper) rotoscoped copy of the 
first 60-ish folios at the British Library, but would like to be able to 
examine some pages in rather more detail than this allows. :-/

Thanks very much, .....Nick Pelling.....
