set of colour filters for the head
SCA310 - analog canon I think
C60 - for Nikon F3 I think
C70 - for Rollei I think
SCA543 - analog Nikon FM-2, FE2, EA, FE, FG, EM, FG-20, F301 to 45CT5 / 60CT2
2 SCA to head cords - don't know what they are called
SCA3401 M4 Nikon ttl/auto/manual
SCA3000 for metz 32, 40 series and 50 series, I believe
Metz SCA 3701 MZ fpr Pentax SFX/SF!, SF1N, SF7/SF10, Z10/Pz10, Z20/Pz20, Z70, Z50P , MZ-3/5/5n/10/50
I am not the biggest expert on Metz dedicated cords but these I have and will part with at very resonable rates if you can use them.
