Hi Dave,I've tried to get to you via your email add ,but I keep comming back Postmaster not delivered...etc. Anyway in answer to your questions...the vac came as it is ,thats to say with no extention tube, to be honest i've never had a need for one, but it's a standard 30mm diameter.The only brand name on the equipment is on one of the hand tools,and thats Hover.
I hope that this helps.Cheers George
