10,000 rpm porsche tachometer, can anyone help?

Hi all, can anyone advise me what this tachometer would have originally come out of and what its worth, its a 10,000 rpm, part number 901 741 302 06, dated 02/1972, also has the following groups of numbers 12v/24000imp and 6zyl/4.1kt and 230/41/8Attachment 213118Attachment 213119Attachment 213120 have attached some photo's but not sure if they are going to display properly. I am located in Australia but will post it worldwide. my email is labourex@bigpond.net.au or my contact number is 0405327025

if for sale, you should probably post a price.

If what Armando writes is correct, and I don't doubt it. What you have there is a reproduction.

The date is way too late to be from a R but the real tell is the 24000imp.

Thanks, ok, well thought it might be the real deal but sounds like its not, it just came out of my race car as we have switched to a 996 twin turbo engine/transmission, so i dont require it anymore, if its of interest to anyone please contact me and make an offer.

Pm sent for tac

You have a factory "Sports purposes" tach; it likely has no redline, or a redline applied externally. Porsche offerred these well into the '70's with the 901 part #. PM me, and I'll tell you how to verify this, plus give you it's value.

Armando also writes this:


"Just because the face of the VDO instrument shows the correct p/n 901.741.302.06 http://www.pbase.com/9146gt/image/134240982 it doesn't mean it is an 'original' 10K tachometer*. Try modifying the back of the can to show the stamped 30000 Impressions, now that's just a bit more difficult. lol"

Ok, can somebody out there tell us what the imp (impressions?) function is?

Also found this sticker on the Tacho that might help identify if its the real deal?Attachment 213126

So what is the value of a real one vs a repro?
