A Trio of Vibrantes

Douglas Rogers has sent us these photographs of his collection of Cammeyer Vibrantes

Douglas has supplied the following commentary: 

The centre one is of course the Royal - it has a hoop depth of 2.875" and 9.5" vellum
 All three have scale of 27.25"
The other two have  9" vellums.
The one on the left (on the right in the back view) has hoop depth 2.75", the other just over 2.5"
The one on the left was built in 1922, and the other - older looking - in 1910.
The Royal I believe was made in the early 30s..
