Apparently, this information came direct from one of the managers at Foma (name can be supplied on request). Hopefully they can come through like they did with Fomapan 200, but I fear this is a more dire situation. Clear base is such a small market that I'm not sure whether anyone else can be persuaded to make it.

All of the cine gauges are already gone from the Foma website, leaving only 135-36.
