I have been given a BSA Model 12 on semi permanent loan. Mainly because it needed cleaned very, very, badly. It was a friend's relative's grandfathers match rifle and was maintained very well, when he had it. Over the years the grease caked and the oil hardened. The proper driver bit, and patient solvent application, allowed me to disassemble it with no problems and no marring. The bore is excellent and the chamber perfect.
The rear sight is a BSA model 8 and functioned fine after a day in solvent. I would like to disassemble it but will not unless I can get a manual or exploaded parts view. Does anyone know where I might find one? The sight is tight and returns to zero with no slop. I have no problems just letting it spend a few minutes in the ultrasonic tank rather than attempting to disassemble it without instructions. It seems to run true and would probably be fine.
I am still researching what the front sight type is and will likely post a picture when the dust and goo is cleared away. It has a beautiful bead on a very fine wire. The kind of craftsmanship you do not see today. Additional inserts are desired once I figure out what type of sight it is.
Does anyone know where I might find disassembly instructions for the Model 8 sight? Or, should I clean, oil, and leave it alone?
