DC14 or DC34 (Leadburn EH46)

See my other post. I’ve 2 broken dysons. I bought another sold as working - the roller doesn’t work and as I paid £40 I’m need to try a fix it off an old machine for repairs. Stupidly I did not check it worked first. The DC14 needs a replacement motor so whichever I can find first to repair and the other can then get passed on as spares.
