Hi, your Your front sight sounds like an original. They are one piece, many old timers switched them out for a dovetail version from Lyman combined with Lyman Model 40 peep. Your 325A was not factory D&T for peep. If you go the peep route find a Lyman Model 40 as the Williams 340 will not allow bolt clearance at the lower settings. Model 40 us hard to find but a rewarding peep sight. If you can shoot scope, do that. If you were in Canada I would trade you a 340 as I am desperately seeking a 325 unmolested.
