I have a friend with a model 54 that he wants me to rebarrel in .308 Win. Does anyone know if this action has a metric or english barrel thread?

Just going from memory they were 1.5mm or 16 TPI. I just can't remember. I did one of the new tactical rifles not so long ago and it was a really stupid pitch. M18x1 sticks in my head. But the old ones were fairly coarse thread. You will probably have to end up pulling it to tell for sure. Schultz & Larsen is just not something we see every day. Or every decade for that matter.

My records show a 26 X 1.8 metric thread.

You might try addressing this same question on NitroExpress. It is full of European participants, among them several Scandinavians with experience with S&L firearms.

Thanks guys. It's also barrelled in .204 Ruger, so it will be a considerable job to barrel to .308.

Just for the information books it looks like 1.015-14. So, 14tpi English pitch.

Hmmm....
1.015" = 2.58cm
Throw your 14 pitch gauge up against a 1.8m gauge and see what you get.

Quite sure S&L's are metric, but looks like 14 is so scary close it dont matter.

I've got a 1.75 which doesn't match but I don't have a 1.8 pitch gauge to check it with.
