Re: Schultz&Larsen M62
The only Iron sighted S&L I have is a .22 target rifle. But I am assuming they used off the shelf sights, like Globe, Solothern or something similar. My front sight uses Anshutz inserts, No clue who made the rear.
Try searching for other surplus type rifles that tend to also be used as target rifles. Swedish Mausers, CG-63 CG-80 etc.
There is a guy in florida that moves a bunch of the above.
Get out your calipers and measure the hole placement, diameter of the receiver etc. Is it side or top mounted... (bet the receiver is 1.33 or 0.66r) You might get lucky and find a sight that fits or be able to get a used Redfield mounted without too many modifications.
Do you by chance have the manual for this? I recently came into a model 65, think the bolts might be the same and would love a schematic or a takedown guide.
