My Dear Bruce:

My 1979 Freya had 7x15 (i think) Fuller Brush ports. Something to
consider. As I was ripping them out they frames shatered. After 30
years me thinks the PLASTIC reached the end of their design life. In
oter words the elements done rotted them,

Get them out or dont go to see and ex[ect to have thme withstand a
good hit. They WILL blow out. Go look at the hinge that attached the
lense to the port. The hinge is just a sliver of plastic that has
become extreamly brittle, in your case, after THRITY NINE YEARS.... my
god bruce plastic that is nearly 40 years old.... humm.
