All of it is top of the line gear. As to value- look what you paid for it. I'm sure the fellow you got it from feels lucky that he got anything for it. If you hit the right market, you might be able to sell it for somewhat more than you paid. I'm sure others will tell you that you hit the mother lode, but these are only worth what the market will bear. Keep it all, and use it.swap it for other items, or try to sell what you dont want. There are plenty of on-line sites to research what you have, just sit down and start googleing.
