Soak overnight with WD40.
Hit edge of trumpet down from rubber with a BFH and chisel, work your way around.

I got a big screw driver and put it in the centre of th trumpet and then belted screwdriver with hammer and freed the knuckle

Like Doc said for the donut end soak it in WD40 and use a chisel or a flat screwdriver to work them apart. With the knuckles I sprayed the WD40 down the trumpet and let that soak for a night then I used a piece of steel rod with one end on the ground I slammed the trumpet down over it until the knuckle comes out the top.
WD40 is your friend :wink:
