Nice XXX Hose!
Very nice hose, John. Does it hold suction? It looks like it might!
The 'handle' is of a later vintage (suction relief, AE+)but it really is, OK, I'll say it, FABULOUS! You might consider changing the handle, there is a retaining spring inside where it rotates that will release it. These can be very frustrating to remove OR it might come out easily. Be certain NOT to bend or dent the 'retaining collar' that is attached to the hose. GREAT FIND!
