In the 1960s, "Bluesbreaker-Pinstripe" grill cloth was purchased by Marshall  through a vendor that also supplied different versions to other British amplifier manufacturers of the day.

Interestingly, each manufacturer and/ or brand seems to have had its own exclusive variation, as the unmistakable "Bluesbreaker-Pinstripe" form appears in numerous color combinations on certain amps from Selmer, Domino  (Vox) and Park  (Marshall). 

EC Collins currently offers the bold white & black 1966-67 Park version--as  featured on the new line of Park amplifiers, produced since 2014.

Also offered, is a lower contrast Marshall "white" variation, which more closely resembles the look of the earlier Vynair cloth, used from 1962-65.

And finally, the very rare "Blue-Pinstripe" used on Selmer amplifiers and the "Green-Pinstripe" used on Domino (Vox) amplifiers for a short period of time, in the mid-60s.  The Blue and Green cloth looks amazing in any custom color application.

All grill cloths--regardless of color--are structurally identical and feature the same tone shaping properties.
