I've just had a sort out of some bits and I've found a set of WM20 cases that are surplus to requirements. They are in good condition apart from needing a good blast, they have the magdyno strap and the remains of a breather, all the studs/tappets and posts for the cam gears. they are a matched pair, the only downside is that they have had the numbers overstamped at sometime, they have the original WM20 stamp, but the other numbers have been overstamped, but they are easily restampable.
I'm looking at £35 for them plus postage at cost which to the UK is £10.58 but I'll send them anywhere at cost. I may have a spare set of postwar ones for the same price if anyone is interested please PM me
