B&H's Mazak castings have a line of raised letters (separated with hyphens) on the undersides or inside pad cups, whereas the drop forged ones have two digit numbers (or two digits with two letters under them) stamped into them to denote which number each key is when it comes to ordering a replacement.
You can see the line of numbers separated by hyphens on the undersides of the LH levers in this photo:

In the UK anyway, the B&H "77" (wood with ebonite bell) and Regent (all wood) from the '50s had Mazak keys, although it turns out some others made for the export market had them as well. B&H weren't alone in using Mazak keys as there were other makers using them on their entry level instruments.
