Here's a resurrection of an OLD thread... :-)
I've recently begun to store all my TECHNIC sets, which range from about 1988 to
present, all have been stored MISB (well, OK, they've been stored in the
original box after I opened, inventoried by bag, and then stored them BACK in
ziplocks that corresponded to original bags -- oftentimes after building the
main model, but always without mixing with other sets).
That sounded terribly anal-retentive. Well, I used to live in an apartment
during most of my post-dark-ages years, and so sets were more stored than built
for a long time... there was a REASON my inventories were once targetted to
possibly become part of LUGNET. But I digress...
In wanting to label drawers correctly, I've gone back and done some research on
certain parts that were "remolded" over time. One of those was the 3650
24-tooth crown gear. My findings are as follows...
There were 4 variations that I've seen.
1977 brought us something very close to the '77 version referenced as 3650a
here:
http://isodomos.com/technica/registry/gear/gear_4.php
The difference was that the center line portion extended further out, to the
point where it would touch the circumference of the circle formed by the inner
curved design (on the photo, extend the center line of missing plastic out left
and right until it touches the "dot" to the left, that's how far out the initial
gear design extended).
The 2nd, 3rd and 4th would be a, b, and c designs as shown on that page.
Note that 3650a was introduced in 1990, not 1994 as shown on that page. All my
sets from that year (8094, 8064, 8850) have the "new" reinforced crown gear.
I need to do more research to determine when the "long tooth" version was
released, exactly.

| Is anyone opposed to my moving 3650a.dat to 3650.dat? If someone later makes a file for one of the other versions of this part, we can do another move at that time. Steve (...) (22 years ago, 27-Aug-02, to lugnet.cad.dev)
