YS-60 strobe rotary switch O-ring: what size?

Hello!

Some time ago I ordered "maintenance-kit"
O-rings for my MMII-EX and YS-60 strobe.

The O-ring intended to seal the rotary
switch of the strobe was rather small -
about 5mm external diameter.
When I started disassembling the strobe,
even before actually disassembling the
switch, I was under groing impression
that the O-ring should be significantly
larger - about 8mm external diameter.

So I stopped, not wanting to
damage the O-ring while taking it out only
to find that I don't have the correct
O-ring to replace it.

Has anyone ever disassembled YS-60
(or YS-50, they look similar
as far as switch goes), looked
at the O-ring and can tell me
what size it is: is it closer to
8mm external diameter or closer to
5mm?

Does anyone have some broken
or flooded or in other way unusable
YS-60 (or YS-50) that (s)he can
disassemble (or is patient enough
for me to e-mail guide him/her
through the disassembly) and
look at the switch O-ring size?

TIA!
