I've never used any of my Makinas for IR photography, so I can't tell for sure. Actually, I've never done IR photography, so don't know how it would work. I assume that, if there are no pinholes or thinnings, it should work. I have had three Makinas, one III and two IIIR. Still have the two IIIRs, and bellows haven't been an issue so far with "regular" film.
As for the lens surface, if it is cloudy, chances are that can be cleaned if it is just some evaporated oil or just plain dust and dirt, unless you can see it clearly scratched...
Serial number, based on what I have seen - not that I have compiled a serial number list or anything, I am just a big fan of this system and keep an eye on the market out of curiosity mostly - tells me that it is a late unit, confirmed by the two square windows. Last time I saw it, serial 93270 was mounted on a chromed Makina II with round RF window. and a lower 102xxx number was assigned to a "Schnell" - German for "Rapid" or "Fast", hence the IIS model - Anticomar 10cm f/2.9. A number closer to yours - 99720 - has been observed on a chromed III with two square RF windows.
Here's a IIS with a neat flash modification, similar to yours but on the opposite side of the lens:
Just for the sake of knowledge-sharing, the highest serial number I have recorded on a Makina lens (actually belongs to an Orthar wide-angle) is 123929 - and serial numbers were shared by all different lenses with a couple of exceptions, so I think it is safe to assume that less than 125,000 lenses were made, out of them about 100,000 are "old style" and some 25,000 fit the Makina IIS, III and IIIR. Not too many of those cameras around, based on these figures...
