I would be careful about buying half weight drums, even SOS. I had Jay make me an oak drum and take it thinner on the lathe, so it weighs about 2/3 the normal weight. Jay told me don't do it, but I went ahead with it anyway. Like he predicted, it cracked in about 5 places the first 2 years I had it, all on the glue lines. That was about 25 years ago and I am glad I went through with it. It sounds and looks great now, my favorite drum that I play every day, but I had to fix the cracks and refinish it. Part of the problem was also that it was originally finished with Watco oil, and I live in the Northeast with wide humidity fluctuations between summer and winter. Refinishing with polyurethane on the outside (only) was a big improvement too.
Thinner shells is the most likely way he made those drums lighter, which means less glue surface and more chance of cracking on the glue lines. I would also wonder with drums that sounded good enough for recording, were that pretty and superlight to carry, why Mongo didn't gig with them. Maybe he thought they were too light and not roadworthy? A lot of Cuban conga de comparsa drums are made thin and light to carry more easily, but all those I have seen that have been transported to the US have cracked and had to be fixed, plus they are not as robust to tune up high. So make sure that the drums have no cracks or all cracks have been competently repaired, and make sure there is no problem with putting normal thickness skins on them and tuning them up to normal pitches. The drums are going on 40 years old, so for that price, you should look at them very thoroughly, or get a money back guarantee.
Also, forgot to say, last year I fixed 4 or 5 cracks in my ash SOS, also on the glue lines. That is a normal weight ash tumba, shrank around the alma and cracked and also had a couple cracks in the bottom area. I take good care of my drums, we play them at lots of rumbas, but again, the humidity swings are the problem. I moved the alma down a little bit so with the cracks closed it was snug but not super tight in the dry winter, and have not had a problem since. Titebond II rocks, but fixing the alma-related cracks in the winter was the key.
