Anyone know what brand of A arm this is?

[nhtc33d]

Hi All, I found these parts for sale and was thinking about buying them. Everything has never been used but was installed and left sitting outside for 6 months. There is a set of air bags,lower control arms,disc brake kit,new ball joints and tie rod ends, and 2.5" drop spindles. The bags are slam 7's and the arms are air ride tech.(this what I was told) Don't know what brand the spindles or disc brake kit are. What do you all think this stuff is worth?
Thanks for any help/advise you can give. Mark
