Saco TRG 41 42 breach threads?

[Bigugly]

As I understand it one of these has metric and the other has inch threads on the breach end.
Any one know which one has what?

I don't know why a Sako would ever have inch threads.

Just unscrew the barrel and measure them yourself.
If you won't ever be unscrewing the barrel, why does it even matter what the threads are?
The threads could even be cruciform threads...

I found this on another site.

I think the L-46, L-61, and L-579 use 16 TPI V-threads.

The L-57 action, is 1 1/2mm pitch Metric. (Approx 17 TPI)

What years were L-46, L-61, and L-579 actions made?
