Paul you are a lucky man. I have been collecting 51 for over 30 years. The price seems to be about £130 at the moment. Was at the London Pen Show last weekend and there were some at £200+. I must admit I have so many, about 500 that I chop and change nibs, or like last weekend buy nibs. (£30-£40) As an accountant I usually use fine, but with a very short name now have a collection of broads to sign. I prefer the vacumatic over the aeromatic purely for heavier flow. Had about 6 made by Mr Kullock in bright colours, and one in silver
