agree wholehearted with you.
I replied to Steve with my continued opinion with it being a "product verification" item, whether it be shore coggins, or other.
He has kindly offered to place it on his webpage, for broadcast.
We may never know, but is fun, chasing.
Weighing the facts as presented........
In a British QV stamp lot
Basic format of a Penny Black (letters in corners)
S & C L in corners
Dummy East Central London Pmk
That's pretty heady evidence.

thanks for the email - likewise I will put the picture on the Shore & Coggins page - perhaps someone will have some definitive information about it
