Hi

I had trouble finding these as they were withdrawn from sale in the UK.
After much searching, via some help from Merck UK, I obtained some from
Leica Sweden, their last seven in fact. They did however have some
complete sets of object markers, including pads. Perhaps you can try
them. Your agents for Leica should be able to get the address.

If that fails, I know that Nikon sell an object marking lens, apparently
including one compatible with the Eclipse series too.

Hope this helps.

Regards.
