Great project, I have been putting together Lee Speed (BSA Sporters) parts for over 15yrs & if I had found that sight I would of snapped it up, it is off the later lighter barreled, plain stocked BSA Sporters & you can see it is extra high to match the standard front sight .
I have Carlsen Highway's Speeder & in that pic you will note its express rear sight has gone with the barrel some time back .
