That AB looks exactly like one offered by Harbor Freight Tools for $10. A few weeks ago I picked up two of these at the local outlet; they were on sale for $4.99 -

They also have a Dual-Action for $20. Parts breakdown and numbering is the same as a Badger 150. I got one of these about 10 years ago; it works great -

MusicCity is right - experiment with lower pressures and thinning ratios; you should be able to do some pretty fine lines. Good luck!
