Hi Momma
Caithness produced nearly 3000 designs and the vast majority were abstract like yours.
The problem with seconds is that they could have been classed as a second as the
intended design did not come out right.
So a paperweight which may not be true to the original design which you have to try and
match against one of the 2000+ abstract designs - you see the problem.
Your only hope is if a GMB member spots your picture and has one of the same design in their collection.
There is a Caithness "bible" called the Charlton catalogue but I should warn you that most of the
the illustrations of weight designs are to say the least - poor !
Good luck
Derek
