Central peep sight

[muffett.2008]

William Dunn, although not his first foray into sight making, the Central Sight patent 17801/34 was the most successful.
The original sight was available and in use prior to the patent date of 1934, but due to a long running patent infringement suite, it did not become commercially available until 1936.
The CENTRAL brand was to eventually overtake most of the sight manufacturers as the preferred option, diversifying into other related accurising components and continued thru three different models,(1,2,3 and finally 4) and several different Marks well into the year 2000.
It proved so popular, that it was illegally cloned in England, and replica brands were instigated when its patent finally ceased in the late 1970's.
It continues in use today, the TMAC sight is simply a robust copy of the original Central 4, serviceing and parts for these sights are readily available still.
