Bought at an estate auction yesterday. It is mostly bronze or brass, does not clean up much with Brasso. It is 9 1/2 inches long and weights 1 3/4 pounds. The wheel is magnetic as is as area where the bottom handle joins. It has a partial mark, first is LG24, then a date 1886, then JDFLL & Sons. and lastly _EV____KETIA. I checked DATEMP for all the 1896 patents, no match and I figured that as I think it is British. The way I think it works is you open the two larger handles, put something in it and then close the handles and then rotate the wheel handle to ??? I hope you are not stumped as I am.
