I suppose every keymaker dreams of making the perfect key and I am no exception. It was however when I restored an original PS213A key for an American collector that I realised the goal had already been achieved. I then made some copies of the original key but in place of the steel contact tongue which had a tendency to bend, I fitted a spring steel tongue. These keys met with very favourable reviews from some very experienced operators and it was then that I had the idea of the adjustable spring loaded contact. I then designed my version of the PS213 .... the PB213. The lever of course is the heart of any key so it and its fittings are identical to the original key, but everything else on the key has been designed with a view to simplicity and ease of production, whilst hopefully retaining some 'style'. Initially three versions of the key were produced, a long tongue with spring loading, a short tongue with spring loading and a long tongue without the spring loading . It rapidly became clear the the long tongue with spring loading was the way to go, so the short tongue was discontinued at Ser. No.10 and the none spring loaded version at Ser. No. 26. Two changes have been made to the key since first production, the lever pivoting arrangements have been simplified and a steel base weight has been included in the lower base in response to feedback that the key was a little 'lightweight'.
