Stuff and nonsense. Eric Beltrando, who knew the man well, tells me that the last owner of Boyer (CEDIS-Boyer, then) glued Beryl lens groups by hand. Literally by hand, he held them in his hand, didn't use a v-block.
And remember,the Beryl is a Dagor clone. By Eric's calculations, a very good Dagor clone.
If anyone read my article on the fotomosaic site, you'll notice I suggest using your tongue to see if the elements are lined up correctly. Works like a charm.
