I have or had a REG catalogue at one point and do not recall seeing this item listed.
IIRC it would have been about 1980 (the catalogue).
Your bottle holder may be an item which was discontinued by the time of my catalogue...
One agent for their products in the U.S. was the Zeus Cyclery Corporation of NYC.
Of the three Rampinelli enterprises do not know if any are still active.
The other two were Cobra tools and ROTO components.
