Anything but buckle on US Diver's Pack?

Other than the belt buckle and belt strapping, are there any other useful parts off of a US Diver's Scuba pack? I have one coming to me and can harvest it for the buckle. But didn't want to dispose of the rest before knowing if I should take some of the additional hardware off it.

Thanks in advance for anyone's thoughts.

I don't know of anything, but you never know what will pop up...

Depending on what pack you've bought, there could be 2 buckles on it. I found 2 like this at a thrift store last year, for a total of 4 buckles. Also, the pack in and of itself is a fairly light sturdy base that might work to build a jet pack around.

Thanks guys. Looks like my pack has only one buckle on it.
