Default ID some transformers?

Has anyone any idea about the specification of these two? They are low-frequency and well-made but I have no idea what they may be for.

The flanges, laminations and bobbins were all off the shelf parts used by various makers.

They could be wound for anything.

You can measure turns ratios == voltage ratios.
Wire gauges will give an idea of currents.
Core centre limb area will give an idea of total power.

The number on the side, could that be an RS part number??

I was about to suggest that as well. It does look like it, though I don't know whether other UK manufacturers or distributors used similar code formats.

It might be convenient to mention the actual numbers: 1472 268 and 293-226 repectively. The latter looks more like an RS number than the former, I think.
