The photos with this post show pictures of a red needle tacho which accompanied a car bought from the US over 10 years ago and were part of a full set of restored instruments with the car.
The unit seems to have been made using an original VDO case as with many repros and reads up to 8,000 rpm without any read line section at the high end. It carries the name of VDO at the bottom of the dial face and looks to be therefore assembled from VDO parts.
On the rear it is clearly not an original VW\T34 unit as it doesn't have the cutaway at the top but looks to be dual 6 and 12 volt.
From the shots of Tachos on the Type 34 register and Pure T34 site it looks closest to a Tim Dapper unit but not an exact match.
Does anyone have any views on who may have created it and what its value today would be so I can sell it on for my friend?
