Nice frame! The BB is a simple cup bearing (non-cartridge) type. Worth keeping it if it's not too worn. First loosen the lock-ring on the left side with a peg spanner or if it's really stuck, CAREFULLY with a hammer and flat-ended punch. Use a peg spanner to release the left cup. Remove the bearings & spindle. Remove the right cup with a correctly sized large spanner or do what I do when they are tight. This is to clamp the flats of the cup in a bench vice and turn the frame firmly but carefully by hand to loosen the cup, which will then be able to be unscrewed by hand.

To remove the stem, apply penetrating oil around the top edge and from underneath into the steerer tube. Leave it to work overniight. Use a piece of wood to protect the stem bolt, tap the bolt head sharply down with a hammer then twist the stem out using a pair of handlebars or broomstick etc. as a lever in the bar clamp of the stem. If it won't shift, remove the bolt completely and use a longer rod as a drift through the bolt hole to drive the expander out of the bottom of the stem. Then twist the stem out and retrieve the expander wedge afterwards by threading the bolt back into it and pulling - use the drift from below to move the wedge higher if needed.

Good luck, the Woodrup will make a brilliant classic bike!
