A question on retro lamps 🙂 Is the Speleo FX2 lamp head a standard Oldham shell with a different switch on it?

I've been sent some photos of one by somebody looking for parts and it appears identical to an Oldham (apart from the swtich). Somebody looking for parts!
Although the photo shown above it looks a bit different. I'm wondering whether the photos I've been sent are an Oldham shell on an FX2 battery.
my orders are to sit here and watch the world go by
