Take all the sheet metal off of it,, it bends easily,, remove the stoker from the side of the base.. unbolt the boiler from the base,, the bases often are too weak from corrosion to use to support the boiler while moving it..
Then you can rent an engine lift, just make sure it can straddle the base,, many of th engine lifts' lower legs are too narrow to get around the base..
PM 'coal berner' he will know the weight of the boiler and base to the ounce !

You may also post the same request on the EFM forum, maybe it will get a quicker answer..
