Hi Yes, it's a base that goes outside the cover rather than a base that fits inside the cover. Since the cover is the "big part" it's the only practical thing to grab onto. The base with the pins coming through it is tough to pull on without getting yourself into trouble.

I think the base will need to be secured and the top pulled off. This is different from most of the OCXOs I have seen.

You need something between the cover and metal jaws to keep it from wicking the heat. Leather works, so do plastic inserts. Keep the jaws as far away from the base as practical. 2) Fire up what ever you have for a major soldering job. Big old tube era soldering irons are the weapon of choice for many. Others use torches. If it's an old electric iron, let it heat for at least 30 minutes. 3) Start working around the lip of the base with the iron. As you heat, the solder will start to run. Wick it out with your favorite brand of wicking material (coax braid also works). You probably will need to make two loops around the part to get the bulk of the solder off. 4) Continue with heat, and use a knife blade to separate the base from the cover. It's a little bit at a time thing. Some parts will go fast, others not so fast. You slowly walk the two parts apart. On the part you have, you may need to spread the base open a bit to get the cover to move easily. First time out, it can take a while to get it done. After you have done a few hundred, it's easier.

I can't see a way that would not make a huge mess (big torch) or not ever get there (big soldering iron). I would really like to be able to get inside of some of these without making them all into trash.

It should be pretty easy to pop open. You'll use up a bit of solder wick doing it?
