NOS Red Needle Tachs are common - (not really!)

Well - first there was Freddy over in Belgium finding his NOS Red Needled Type 3 Tacho a few weeks ago.
























Then - guess what - I found one too. Same tacho - different box, but NOS all the same.
6 volt - uber uber rare in the red needle format (and not so common in the white needle either!)

Now the question is - do I install it, or do I keep it on the shelf - the answer will be with you tomorrow!
