Sherman., I picked up the same set. I'm going to try it for 30 days.
These look like a badger 150 but some of the parts ARE NOT interchangable.
When I bought my Badger it came with three needle/nozzles. I was going to put the fine needle/nozzle in one of the knockoffs. The needle fits but the nozzle does not tighten down enough.
The paint bottle do fit.
I really like the manifold with the holders. Very nice.
I assume you can attach the compressor hose to any of the connections. They are not labeled as in or out.
