We introduced hand-embossed serial numbers to our bags in 2010. Prior to this we had only produced a couple of small runs, no more than 15 of any one bag.

Our batch production runs are still very small; 50 or 60 bags at most. Even so, we feel its good practice to allow our bag manufacturing processes and provenance to be fully understood by our customers, if they so wish.

When interest in Herdwyck No.10 tweed increased, we thought it prudent to record the details of manufacture. When and where the bag was made and by whom, which batch of leather and tweed were used and other details can all be gleaned from the serial number.
