Rob - If the Leica flash has a light sensor on the body of the flash, it can
work with the OM-1n. No need to worry about 'delicate electronics' as the
OM-1n uses a -mechanical- switch to trigger the flash when the shutter
curtain is fully open (1/60 and below speeds). I don't know the trigger
voltage of the SF20; you might be able to find it on the net somewhere, but
if it is a fairly new design (post 1990 or so) it is probably low enough for
electronically switched flash contacts. IIRC the suggested voltage is ~6VDC
or lower.
You won't get the in-viewfinder flash signal that the contacts of the T-20
and T-32 will illuminate, but if you keep 'your other eye' open you'll at
least know the flash fired...<g>
