I picked up this Abu 501 from a local junk shop yesterday.
I payed £20 and am quite pleased with it.
Its had use and has had one or two knocks and scrapes, but overall, not in bad condition at all.
I have bought it to use and compare to my 506 and 506m.
I cleaned and re lubed it yesterday and it seems to be running well.
However, I believe that there should be a spring of some sort, underneath the tension knob on the handle.
There isnt on this one.
Does anyone on here know where I might get a spring ?
And are they really necessary ?
All the best.
Neal.
