Hi my apologies. Some of you were absolutely right about the first machines credentials. It is a 28K. For some reason I must've had a dyslexic moment because when I re-checked the serial number on the listings I was way out.
Yes it's quite funny having an original engineer rather than a 'Chinese factory copy'. He's quite wizard with sewing machines so I have great expectations of him. Both machines have their cabinets and various feet with a bit of wear and tear but I'm sure I can locate someone who can greatly improve them. At the moment I'm busy with other family stuff and not had time to get the machines to John. Anyway ladies and gentlemen the advice I'd really appreciate from any of you is what can I do in the interim to minimise the very musty smells in the machines and cases without damaging them. Onions in a fridge help neutralise smells, just wonder if one inside the opened cases would have the same effect.
