You've got me worried now Sebo! They sit in the loft dismantled wrapped up in bubblewrap. Loft is a bit insulated, but I imagine it gets cold up there.
Will ask my parents if I can use their recently cleaned out loft, it's never cold up there! Got to get some boxed away, running out of space at the flat now, have about 10 machines sitting around. Need to sell a few/give one away too!
Jake - seriously tempted to just wipe down any visible dirt, lightly polish the plastic up and leave the 1436 as it is. Can't wash the bag anyway as the spring holder is built in, plus it doesn't need it! Will see what condition the 1426 is in when the seller actually responds to my question about payment!
