REFILL Campingaz CAMPING BOTTLE 901,904,907 FROM BUTANE GAS CYLINDER 21mm clip o | eBay
Anybody used this kit to decant from 15kg calor to 907 camping gaz. Considering due to lack of availability. Sorry if link doesn't work.

I use the same system (adapted for gas tanks from almost all over the world), no problems except for legal considerations of course.
A hint if you do not have a weight scale: put the receiving 907 bottle in the water when you fill it, once it arrives to roughly neutral buoyancy/slightly sink, it will be filled with the correct amount of gas.
Attached, filling from an unknown African bottle




edit
some types of bottles have some sort of safety device which prevents from using them as donor, namely in the US I am told, not sure about the Calor you are referring to.
