Because it is a slip-on fitting (metal-rimmed) to the underside of the condenser it is easily lost (how I don't know... but it apparently must be easy for folks to do in the dark). I've seen many more Focomats without the anti-Newton glass than with... and getting a spare glass is very difficult... they're like hen's teeth. I've only ever seen one for sale in the UK for £80 ($135) about 5 years ago... and as the Ic is probably more available on this side of the pond one would think that there were more a-N glasses around also... but no.
