This one came up on U.K. eBay a week or so ago and I happened to see it purely by chance when browsing at other Enfield bits and pieces. It was was priced @ £30 buy it now or best offer which also included a pull through in the deal. I didn't have a clue if this was a good price or not but knew that they didn't come up for sale very often. I offered £25 and the vendor counter offered @ £27.50 for the 2 items which I agreed to. It would seem that I got a good deal if mainly by luck.
