Hi Sil the frame that you mention is manufactured in the U.K. by Peter
Fredrick and we have tested it out on the creative imaging courses given
by Peter at the Kingsway College in North London and i can vouch for the
efficiency of them.The baseboard consists of a layer of very thin rubber
into which air is pumped through a bulb thus forcing the negative and
paper into tight contact he makes them in a number of sizes and they
also have a four hole punch and registration pins affixed . I know that
he is sunning himself in New Mexico at this moment in time but he can be
reached on pete@fotemdemon.co.uk
