I just picked up a Svea 123R stove from a friend but it doesn't have a windscreen or the pot which goes on the top. Does anyone know where I can pick those up?

Bought my first Svea 123 in 1976 and used it for about 15 years until my BIL lost it. Found one on E-Bay a few years ago to replace it. There are always a few on there, cook kits, etc. When I bought mine all those years ago, I had the Sigg Tourister wind screen/cook kit combo that worked a little better than the "Stock," brass wind screen. You may find one in an old school backpacking or outdoor equipment store online too?
