Help with lost ISO for a lost and found film

[Fintan]

This is a long shot I know but anyway.

I lost a roll of film that I shot last september and just found it last weekend. It's a roll of 220 Tri-X or 320 TXP.

It's of Iggy Pop performing on stage at a music festival here in Ireland. Shot on a hasselblad with a 120mm lens and much to the merriment of the press with me in the pit.

I shot it at 1/125 at f4, thats all I know. I didn't record the ISO and I'm kicking myself for not doing so, but glad I've found the film anyway.

The stage was well lit and there was still some evening light, not much but some.

I've looked on flickr and see some shots taken around the same time. Some like this;

Can anyone suggest an ISO to dev this film at? I'm thinking 1 stop / 640

Thanks

I can't; but I bet Les can.
220, that's long enough for a clip test.

I should have mentioned I'd like to avoid a clip test even though theres 24 shots on it.

Yep will ask Mr McLean tonite, I hope he doesn't want to demo clip testing after a night on the Guinness

Diafine should get you something useable.
