Yes: I had the same problem with an E-Bay A24 and an A16 back ! I had to get help from a fellow camera Club member who is retired Professional with a 'workshop' and we put some oil on the 8 screw heads, then he gave me some black foam, and I took it all home and loosened the 8 screws (put them into a developing dish in case I sneezed and lost them !) then cut out a new foam seal with a razor blade and made a new plastic bit from a bit of 120 film and it all WORKED and out in the bright Sunshine (yes, UK had some SUN the other week !) there were no more leaks on a test bit of film .
