followup to flash with pinhole question

Hello:

Took some full moon shots with 35mm pinhole and color film...it it takes
me less than 50 years to finish this roll, I'll see how they come out.

Anyone have any familiarity with or idea where to find out Guide Number
for a Nissin 28TX Thristor-SO flash (no manual-info not on back)?

I took it apart to hardwire it for a project and lost the little slider
that gives ISO-f-stop-distance settings.

Thanks

Murray
