Need a little help!

I have attached a few pictures of fly lines that were given to me.I have no clue on there origins nor can I find any info online.:confused:
If anyone has knowledge about these please let me know.

Oh by the way I’ve got a box of Dunkin doughnuts and coffee for all!
Cheers
Big Dan

They appear to be shooting heads and a running line. The running line should be attached to your backing as usual and then the shooting head is connected to the running line with a loop to loop connection. You may have to add loops to both. This system allows one spool to handle several different sink rate lines or floating line.

Thanks so much gentleman…That link is very helpful.
