HI all,
Recently picked up a nice condition model 75 Sporting .
I’m perplexed by the front sight.
Its a Lyman 77r.
I’m fairly certain these where not an option on the Sporting models.
As such I bartered a better price.
It has a Lyman 57ES rear sight and a dovetail slot blank filler on the barrel .
The stock appears to have a factory cutout for the Lyman 57ES.
The barrel dates the rifle to 1955 and it has the grooved reciever for mounting a scope.
Did these ever come with a Lyman 77r and if not how does this affect value?
Sorry I can’t post pictures here as I am not yet a full member .
But plan to be as my number of vintage Winchesters is increasing.

Your Winchester Model 75 Sporting rifle would have come originally with a Winchester 103B front sight, and the Lyman 77 is a later addition. I don’t believe that adversely affects the value, as the Lyman 77 is a much used and much sought after sight that can easily be sold. The Winchester 103B is a fairly simple bead front sight and finding one would not probably be very difficult.

I would love to see a picture as the 75 Sporting rifle has a front ramp with elevated dovetail for the 103B, a Lyman 77 mounted on the ramp would make for an extremely tall and ungraceful-looking front sight.
If it is easier, you can email your pictures to me and I can post them here for you. Abendshien at AOL dot com.

Thanks JWA.
I will send some pics out to you tomorrow.
You’re right,
Its rather ungainly looking but the line of sight is quite comfortable for me from an off-hand position.
I don’t think it can be retrofitted to the original front sight as the Lyman is fitted to a scope block type mount screwed into the barrel.
It appears to be the correct mounting block for the 77r.
