P.k. thomas modelling kit - REF. 583/KIT.AL

The P.K. Thomas 583.AL line of instruments has had a recent revamp. The instrument tips have been redesigned following the shapes of the original models. Now they are finer and more accurate for even better modelling. Compared to the previous line (581), the colours on the anodised aluminium version have been updated to be closer to the original sequence devised by Dr Thomas.
