Pulling apart an FC bench for a re-trim and came across this, not sure if it is significant or not :-\

Sure is, the part # is there, ring em up & order some more :)
I've not seen that before, nice one
Nice to see these old labels. Its the way things were. You don't always see behind the innards of a seat.

It would appear that GMH have in this case used a hessian bag or sack which was supplied to them containing other trim pieces. I have not seen this on a seat before but the label does not make any sense other than that.

It was nicely centred too.
