I have sent an e-mail,I thought somebody here might know.This appears to be the same tonearm that was on the Revolver Rebel and the Ariston Q Deck.It was made by Jelco of Japan and they claim they no longer have any records of these oem arms they produced,over 20 years ago,they stated.The Sota Moonbeam is still in production and it looks like exactly the same arm.Sota infers it is their own original design,but obviously...Jelco now offers the SA-250 arm on their site but only the curved arm tube and the detachable head-shell seem to vary from the old design.Stefanl
