The article on the Sd Kfz 251 halftrack series said that the Type C came out in mid-1942 while the Type D came out in early 1943. I could have sworn I saw books saying that these two versions came out beforehand. So what's the story?

According to this article :

http://www.panzernet.net/panzernet/stranky/polopasy/251.php

The "C" variant appeared in early 1941, and the "D" one production began in August 1943...

According to that article :

the "D" entered production in July 1943...

According to Jentz (PT 15-3-2), D production started in May 1943. In PT 15-2-1, he gives early 1941 for the first deliveries of production Cs.

Wikipedia is a open source platform. i.e., anyone with a PC can edit it. If I were you, to verify facts I would use other resources. False misinformation can be a curse and the results will be far from what you expected and what you wanted.
Just look at Nov 8th, and you'll see what I mean.

Just don’t tell me there is no real Frenchy! 😠

Excuuuuuse me while I go hack some changes 😈 … just kidding! Hehe!

Last time I've checked it looked like I was real Mike

For most part, Wikipedia has slowly been getting better. I think there is now more oversight of the changes being made and if, for example, someone were to edit an article with false information or delete the information within the article, the change will be reversed or the previous version restored. I still wouldn't use Wikipedia as the definitive source for information but it isn't too too bad to use as one of many sources. The good thing (which has is also a bad thing) about Wikipedia is that anyone can edit a page. So that also means that we, being the sticklers for absolute historical accuracy that we are, can go in and correct inaccurate information if we find it (and have a reputable original source for the information). I've gone into a few articles and corrected grammar on occasion.

Indeed, it seems Wikipedia has been getting better, still I can say that I have only once contributed some info (on the M113 APC in Greek service) and its been stuck as "verification needed" for 2 years...
