Many of their cameras could be supplied with this new Unit shuttter fitted including the Royal Ruby, Special Ruby etc but these weren't Relex cameras. The older Unit shutters had adjustable tension, like the T&I and used the same ratchet shutter speed indicator (as my Avatar), so needed two adjustments one to wind and re-tension the shutter, the other to adjust the tension to change the spped. The 1910 Unit shutter is similar to our Ruby Relex cameras, one winding key, they still used the key in 1921 but by 1924 it was a radio style knob.

So in 1910 there's also the new Ruby Reflex with the newer "Unit shutter".

The camera still looks the same in a 1921 advert. So I guess what the site owner calls the Ruby shutter is just in fact the newer type of Unit shutter.


My head is now spinning

Didn't you say yours was a quarter plate?

Mine is a 3 1/2 by 2 1/2. That might explain some of the differences. That also means neither 'special' nor 'Junior' refers to the plate size. I'm beginning to think they just strung as many brand names together as they owned the rights to and stuck them on the name plate...

My camera came with a really nice Taylor Hobson Cooke Anastigmat 5" lens, which is not in a sunken panel. I've also got a Carl Zeiss Jena 15cm Tessar which is a nice fit.
