Hi. I have for sale an RV1s. I`m afraid I dont know much about it except that it was fully functional last time it was used about a year ago. It does come with feeders (3 of 10*8mm, 1 of 7*12mm, 2 of 10*8mm vibrating, 1 of 3*24mm/2*8mm) in varying states of repair. Some look ok, others look not so ok.
It is located in Weston-s-Mare so if you are local, viewing is recommended. Or even if you are not local, and just fancy a day out by the sea!!
Feel free to message me with any questions, although I`m not promising to have the answer as I have not personally operated this machine, and I am not familiar with them.
Will post some pics later or can be mailed on request.
Cheers
Paul
