[Milsurplus] Help with plug ID

[swkb4dmf at windstream.net]

Gang,
  I could use some help with identifying a few connectors that I have on eBay and was hoping some of you may know what they fit. I've tried all the usual means and even quizzed a few friends about it already with no luck. It always helps to tie in the rigs they fit with the title and description to help people find it when searching. I've listed these off and on several times with no luck and would like to get rid of them. Any help or advise would be appreciated.

The numbers are: PL-71, PL-72, PL-96, PL-98.

If you search those numbers in Collectibles on ebay you will find the listings with pictures.

Thanks in advance,
Steve
