41 forum posts 18 photos | Hi all found this in my dads old tool box. Its a basic but very well made angle finder/copier. Made by E R Watts and sons London There are no gradations at all but what is intrigueing about it iswhat appears to be a "spy hole" (4.0 clock in picture) that ges all the way through. This component is knurled and unscrews I presume to clean the lense. Anybody got any ideas on this. Regards Arthur |

There are no gradations but one interesting feature is what appears to be a "spy hole" at 4 o clock in the picture. This component is knurled and unscrews I presume to clean the lense. Anybody got any info on this? Edited By JasonB on 02/06/2020 20:28:36 |

![]() 1971 forum posts 108 photos | Hello Arthur, the graduations are engraved onto a glass plate that is viewed through the knurled eyepiece. It may be the the glass plate or the viewfinder is dirty, especially if it has been used near cutting fluid. If it's of interest I can put up a picture of mine. The company eventually became ;Hilger & Watts', a well known name in optical equipment. Brian Edited By Brian H on 02/06/2020 20:16:44 Edited By JasonB on 02/06/2020 20:28:50 |

Is the correct name a 'universal bevel protractor'? I have a similar unit made by Zeiss and called an Optical Protractor. Emgee |

1833 forum posts 241 photos | Hi Brian Just release the clamp lever and rotate to the desired setting viewed through the aperture when holding the device up to the light. It is pretty stiff to move so it is positive when setting, no chance of it moving before the clamp is set. I guess yours works in the same way ? Emgee |

![]() 1971 forum posts 108 photos | Yes Emgee, just the same, and the screw at the lower left of the picture locks the whole thing in position. I don't use it often, it just seemed a shame to throw it in the scrap bin. Brian |
