Central peep sight

[Strangely Brown]

BTW, unfortunately (or maybe fortunately) I also won a micrometer sight that was identified as an "original Svenson rearsight" with a mounting block on fleabay.

Anyone know anything about these babies? Can't find out much about these, except that they are described by some as the predecessor to the RPA sight. I think George Svenson was one of the founders of RPA Precision Rifles.

George Swenson was an American who worked for John Wilkes in London, a very colourful character who managed to get banned from Bisley for using a sight type that at the time was illegal (or actually not approved by council, although I believe the year after they accepted it!)
After his suspension he developed the rifle we know as the Swing and called the first model SIN 71, this was in effect sticking two fingers up at the NRA at Bisley by referring to the model as the Sin of 1971, the year they banned him.
Whilst at John Wilkes he invented a rear target sight which carried the Wilkes name and then later his own name. An older friend of mine owns Swing No.98, but thinks it was nearer No.35 as George liked to "up" his production to make it look that he was selling far more than he really was!
He went back to the states some years later and an ex buisness partner of his went to see him on hearing of his ill health, asked on his death bed if he had a message for anybody at Bisley he replied, bugger Bisley!

Calfed, I note that your Central has "7.62" just under the elevation scale, as does the one I inherited from my Dad. I was under the impression that this indicated it was set up for 7.62x51. (I know he used his on the 7.62x51 Grunig I also inherited). Is this true, and if so, would there be any issues using it on a .303?

Just use it in the normal way!
obviously don't use the yardage scale because that will be out, I usually zero at 200 yards and then use the come ups for whatever the ammunition type gives me for the distances I'm shooting.

The only difference in sights marked .303 & 7.62mm will be the yardage scale. They will still give the same MoA (minute of angle) regardless of what ammunition they were designed for.
