Harry if its any help the "1" in the forty-one it typical of the German number style(the extended hat if you will that often makes a german 1 look similar to a seven). 07 70 fits in with the date and often the other markings have been removed in further finishing processes. Is there any other markings on the back

Thanks to all who took the time to look and respond to this thread. I have learned a great deal; very impressive the knowledge out there. In an attempt to finalize this I will have a tire removed, clean all dirt and weigh a bare rim and post the results soon. Harvey, yes my intent is to sell the wheels; I'm going to sell my 66 911 for which I bought the wheels initially, they are too small for my 73 E. Jim

Real Fuchs vs. Replicas
 

OK, I had the tire removed from one of the wheels. I cleaned the wheel surfaces (front, back and inner rim) and left the valve stem and wheel weights in place as I intend to re-mount the tire. I weighed the wheel three times on a digital scale, I had to add an object of known weight (20 pounds) in order to get the scale to register. The first corrected weigh was 11.4 pounds, the second was 11.2 pounds and the third was 11.3 pounds. The wheel weights are 1.5 ounces total and I assume the valve stem at 0.5 ounces. I don't know if this clarifies the discussion on these wheels or complicates it; I look forward to hearing from those of you that know more on the subject than I. I have attached a couple of the pictures I took of the wheel in it; stripped state. Thanks, Jim 360-372-2874.

Are Fuchs with Hearts more desirable than those without?

Early 4.5" fuchs don't have any stampings at all, just a dye stamp. The stamp could be lost after 45 years.
4.5s are very valuable at least 5k in usable state (not necessarily pretty).

Jim,
I believe the "770" and "670" are the date codes on those wheels. Indicating a July, 1970 and June, 1970 respective production dates. Typically these dates precede the vehicle production date slightly. I believe later wheels had a 4 digit code (week number and year) like "4585" indicating a week 45, 1985 production.

That said, I'm not familiar with a 15x5.5 Fuchs on a 1971 model year car though. I thought the wheel options in 1971 were (4) --> steel, Mahle 15x5.5, 14" Fuchs and 15x6 Fuchs. I see Harvey noted that the markings are consistent with service parts available through 1970, so this makes good sense!

There is a transition period with the 15x6 'deep six' Fuchs. Early production versions had 'hearts' and later production versions did not. In reality, the non-heart 'deep six' 15" Fuchs are more rare and should be more valuable as a result.
The real value is found in condition and date code matching with vehicle production dates. If your car was built in the range of 'heart' Fuchs, they should be more valuable to those who put a premium on absolute 'correctness'. If your car came with 15x6 deep six wheels and was produced after the cut-off for 'hearts', you will have a more difficult time finding non-heart 'deep six' wheels which are correct for your car (because they made fewer of them) making them more valuable in a supply vs. demand environment.

That said, a matched set in original finish is quite valuable in either case to the right buyer. Perhaps a slight premium for non-heart 'deep six' wheels based on rarity.
