The T90 is capable of stop down metering.... Hans P.S. today, most of my FL lenses are used on a NEX3...

Berndt,teries... I still have 2xFT QL bodies for sale... It is the original body meant for FL lenses, even the lightmeters work... (that is, if you have the right voltage, which I still have, buying some of the last Varta Hg-batteries...) Hans

O yes, it is certainly a Tessar. Due to the litigations DDR Carl Zeiss lost their right onn the Tessar name in the West (en mostly in the East). So, T for Tessar (like S for Sonnar, Bm for Biometar, Novonar for Novar). Next to the T is the Quality Mark 1Q for the 1st class product of the DDR.
This T is not to be confused with the red-T mark (or red-delta, red-V and the likes) of early post-war cameras, meaning it was coated - quite a different story, and books have published about it...

The term Novar was first used by the ICA company and were numbered. You can find them at least until 1927 also on Zeiss Ikon cameras after the merger. Late pre-war and post-war Novars are trademarks of the Zeiss Ikon Company, not from Carl Zeiss. Mostly they were bought from Steinheil or Rodenstock to be used in a more cost-concious design. The DDR branch of Zeiss Ikon lost its right to use the Novar trademark during the legal battles of the fifties and the homophonic 'Novonar' was adopted.
Although 'only' a triplet can produce fine results; I like them most in the Ikoflex line.

Welcome Jack, And we like to learn more from you as Chines cameras were never imported on a sizable scale here in The Netherlands. Hans

The mortality rate must be very high indeed... Almost impossible to imagine.

As this thread is also about HF, it is time to mention the extreme toxic behavior of HF. Only use it within controlled environments, use proper labarotory gloves, use teflon as a container and NEVER NEVER get it to touch your skin! If so, run for the hospital!
Only from experience: I used to separate AL2O3 (sorry, no subscripts here) - that is Corundum (Ruby and the non-red variant Sapphire) from its granitic environment; literally boiling the granite by submerging it in concentrated HF. Quite spectacular...

Small correction here: US terminology consisted of 4 formats: A (16 exposures of 6x4.5cm - 2¼"x1¾"), B (11 or 12 exp. 6x6cm - 2¼"x2¼"), C (8 exp. 6x9cm - 2¼"x3½"), all on 120 rollfilm, and D (8 exp. 6.5x11cm - 2½"x4 one-third") on 616 rollfilm. This D size format disappeared after WWII.
Zeiss Ikon used the numbers without a postfix for type A cameras, like 521; the B cameras had a /16 postfix (like your 521/16), and used the /2 postfix notation for type C cameras.
As your 521 is certainly a type B (6x6cm) the proper 'Bestellnummer' is 521/16. Maybe it is not legible... BTW the 'Bestellnummer' is the code for a distributor to specify the gear he wanted to buy from the Ziess Ikon company, and translates to english as 'ordernumber'.

Happy birthday Doug, in the 1st place.
Your Ikonta is a 521/16 (6x6cm rollfilm), first encountered in printed prospects February 1939, and as the focal distance is measured in cm, it is a pre-war version. It might be unreadable, but on the side the bodynumber was imprinted, 1 letter followed by 5 numbers max. From this bodynumber maybe a better production date can be given.
Nice to see a camera like this one back into useful life!

Hard to say, from the photograph alone. It might be (induced) imperfections of the coating, which is generally speaking not too bad; it might be signs of fungus, which is - most of the times - BAD.
Most favourably, they are just reflections - which in the case above, I doubt.
Only in close examination you can tell, so , whwn in doubt, don't buy it, or agree on a refunding scheme...

The Novar is a triplet indeed; bought by the Zeiss Ikon company at Rodenstock or Steinheil. At the time Zeiss Ikon tendered a design at several companies, including its parent company, Carl Zeiss. Depending on the cost constraints it bought at different companies.
Nice pictures, you're living in a picturesque environment!
Hans.

Stephen,
That is the kind of shop we're all searching for!
Here, in NL, when these kind of shops grow bigger - they do because of the economic climate, where more and more people buy second hand stuff - the trend is to establish one of the outlets as a 'luxury item outlet'. The most valuable things will be offered for sale there.
Even when the prices rise, I found a Contax lens set Planar 3,5/35mm and a Triotar 4/8,5cm for €70 which is very expensive for the trade shop but for me a very good find! Hans
