Since I had the mags apart I replaced the spring,cleaned up the dirt and rust and tried them out.
All functioned fine even tho there is still quite a bit of 'play' in the mags when inserted.
I will have to 'build up the catch to tighten any further.
In the mean time I recieved the DSA used thirty(converted Bren mags)rounders and they were super clean with a new heavy finish ready to load and use and store right out of the box.Insert mag,pull up,click,nice and TIGHT.It fits like a mag should.
The 15$ more I spent on the DSA mag was worth it.If I were setting up an assembly line and refinishing a load of the surplus mags it might be fun,but the hours spent working on refinishing and rehabbing mags can be better spent shooting or working on weapons.IMO
My vote:DSA
