This little Field is not a conversion. I have seen it and studied it and Matt has researched it very thoroughly it is not a reproduction or a conversion. This is the real deal it was one HELL of a find.

Interesting to see a gun made by my Great Grandfather William Field of the Field Rifle Company, Birmingham.
My Cousin, Martin, has just published a book called William Field which tells the story of William Field, Gunmaker of Birmingham - His family and descendants, which is available on Amazon which might be of interest to you. He would also like to know more about the gun you have bought.
