SunTour GT derailleur w/ no date code用re-71?
I made it out to Portland and am working to get my Fuji Finest working. I think it's a '71 or '72. I pulled the derailleur to clean it up a bit. It's a SunTour GT, but I couldn't find a date code. I'm used to seeing a two-letter code on the back parallelogram plate. The Vintage Trek date code table shows "N" as the earliest year, 1971. Would the lack of a date code imply an earlier manufacture date?

disclaimer: I have no answer to the question. I'm just here to pull the discussion off on a tangent.
Specifically... I've never paid attention to date codes on SunTour stuff. I can imagine it being useful on the nicer parts, like the Cyclone derailleurs. I've noticed small variations in the first generation Cyclone rear derailleurs, and should probably figure out what the sequence of these changes was.
I wonder if anyone cared enough about the low-end steel derailleurs to bother stamping date codes into it.

I have a 1st gen. Cyclone rd with no date code, so not necessarily.
Velobase shows 1972 to 1973 for the GT, but there may be earlier versions. I have what appears to be an older GT cage grafted onto a V-luxe parallelogram. There are no entries in VB for such a cage.

IIRC, the Finest OEM rear derailleur was a SunTour-V, not a V-GT. I suspect a previous owner installed the V-GT to allow wider gearing.

Here is the SunTour V derailleur from the Fuji Finest I just received. No date code on it; the frame has a 1972 serial number.

Not a GT with those knuckles is my guess. I looked at pics of the Suntour 7 which has more steel, but no match. Take a look at the Suntour Honor and I think we have a match. Honor with some GT parts grafted too it.
Edit:
I stand corrected after looking at Disraeli gears website. Some early and late ones depicted look just like the OPs unit. It is so different looking than the ones with aluminum knuckles. Perhaps I was mixing it up with the the V-GT.

Thanks, folks. In the end I stopped worrying about dates and hung a Cyclone GT from the hanger. I didn't even know its date code.
Still, nice to know not all SunTour derailleurs has date codes.

While I also, er, 'honor' the V as a pinnacle of Suntour performance for the era (raced on one back in the 80s), the V-GT should be respected for being able to do what the V can't - wrangle really large freewheel sprockets.

Note that "Finest" has two meanings here. You might be thinking of the dictionary meaning, while in this instance it's the model name, "The Finest."

The cage's shape appears to be that of the 2nd style 4600. However, the adjuster screws have the 1st style locking springs vice the 2nd style's plastic inserts.
I wonder if Suntour "slipstreamed" a redesigned cage into the earlier model during production before changing the adjuster spring locking system, or if a damaged cage on a 1st style Suntour GT was later replaced with one from a later version.

The earliest Maeda Industries date code I have seen reported is NC, but this was on a freewheel on a 1972 Katakura manufactured frame for Nishiki Professional.

The earliest Maeda Industries data code I have seen is NI, again on a freewheel.
maeda 8.8.8. freewheel
Edit: I think the derailleur date codes came after the freewheels.
