Double Bass Various guts - ID please?!

[eh_train]

Hi,

A friend has a bunch of gut strings that he wants to sell. Neither of us are sure what they are. All appear to be older, and some are new-old-stock. The Artone package is a clue, but it's not clear which string, if any, is an Artone...

Any advice re what they are would be most appreciated!

Thanks,

Paul

I know the red one is an artone. Other than that I don't know
