Thanks John. I could see some of the grain in the one of photos that I looked at, now I think about it. I had not realised that the 3200 films had a lower nominal rating.

I don't need that speed though... we're having a stonking hot summer.

TMax P3200 is a multi-speed film with a nominal ISO rating of 800-1000 depending on exact chemistry. It's intended to be "pushed" and was designed for push-2, hence it's name: P3200. Based on its behavior at push-1 (EI 1600) in the past I don't believe I'd want to use it at its nominal speed. At EI 1600 it's much like Tri-X Pan in grain and latitude. Latitude would be much too wide at its rated speed (ISO 800) resulting in much lower contrast than I care for. Grain increases and latitude narrows slightly at EI 3200 compared to EI > 1600.

In this case (the glassworks) I metered various parts of the factory and used it at push-2 (EI 3200). As a result it required push-2 developing by a full-service pro lab and incurred an additional cost. I don't recommend using TMax P3200 outdoors in daylight. It handles much better under man-made artificial lighting indoors. Ilford makes a very similar B&W film, Delta 3200. It also has a nominal speed rating of ISO 800, and like TMZ it is intended to be pushed. If you've given up on TMZ, you might try the Ilford. I used a couple rolls of the Ilford and went back to TMZ primarily because I try to use it at EI 1600 indoors if possible, and want "Tri-X" type appearance it renders at that speed.
