This is the first tonearm of Denon Columbia, manufactured for NHK broadcast station in 50s year. It is long version 12 inches tonearm.

It is not Denon Corp, it is Denon Columbia which is early of DENON Corp.

This is very early version of DA-303. It is medium high mass tonearm, perfect matching with medium compliance

and high compliance mass cartridge as DL-103, Audio Tehcnica vv..v

This was manufactured for using with DL-103 cartridge, so I highly recommend this for DL-103 fan. This is professional version with long armward.

Effective length 282mm, overhange 12.5mm. IT comes with original headshell and very beautiful condition.

You can use it with Denon DL-103 or any other cartridge.

there is also a DENON DA 305 in a box for $500
