Now I thought I knew most of Flanders and Swann, but 
'all unperforated' doesn't bring anything to mind. Care to
explain (off list if it's not suitable for the general public).

I did find it mildly amusing that the Facit 4070 service manual
refers to totally blank tape -- not even feed holes punched -- 
as 'virgin tape' ;-)
