A new 3D is around a 48,000,000 serial which means Maglite has produced around 48,000,000 3Ds as of this post date. Mag Instrument will actually tell you the date a light was produced based on this serial number although I have a Quick Dating Guide that will give you a rough idea without having to go through Mag.

The secondary update was the relocation of the o-ring from the head to the barrel. Early C cells had the o-ring located in the head. This was troublesome as the o-ring would wear when the light was focused as it past over the threads. This would cause water to get inside the light. I believe this was an oversight during the original design and was rectified after numerous service center complaints during the run of the C cells up until 2003. Shown below is an example of the o-ring placement on a 1981 to 2003 light on the right and a 2003+ light on the left.
Unlike the D cell lights the addition of the panther logo did not signify any design changes. Maglite simply started using the bezel in 1992 when the D cells change over and has used that same bezel ever since. 1992 to 1995 bezels will have a TM next to the Panther as the trademark was still pending and 1996+ lights will have an R with a circle next to the panther. Bezels, lenses, and reflectors always interchanged between C and D cells. The only way to tell the new and old lights apart is from the serial number.

All parts will interchange between old and new lights with the exception of the heads and switches. A new style head will go on an old light but because no seals exist the light will not be waterproof. Old style heads won't even thread on to new style lights. The switches, with the exception of the retaining ring vs. clip, are identical but Maglite doesn't sell retaining rings or clips by themselves so you'll likely have to buy a new switch instead of interchanging them.

I should also mention that the barrels are marginally thicker on the new lights by just about a tenth of an inch or so. A lot of the early C cells I've seen are dented so I'm guessing the aluminum extrusion thickness was increased just slightly when the changeover happened to increase durability. This is the opposite of D cell lights which saw both outside and inside diameter reduced. This is because C cell lights were always extruded whereas D cell lights were originally made from aluminum pipe.

Also in 2003 5C and 6C lights were discontinued. Only a very small handful of the last 5Cs and 6Cs had letter serials. I did a post about these here but basically they were such slow sellers that they were discontinued. Like other discontinued lights they are popular among collectors and often sell for 2 or 3 times their original price.
