[Leica] Looking For M (240) Plate

[Robert Baron]

I'm looking for a plate that will attach to (not substitute for) the bottom
of the Leica Handgrip # 14496 (not the high dollar multi-function unit)
which is attached to my M (240) so I can use it with quick release devices
such as found on my Arca-Swiss tripod head.  I've queried what I consider
the usual suspects (Kirk, RRS) and so far haven't found what I'm looking
for.
