Yes. EFKE produced many things for Maco. Among others all 127 films. They also produced many things for us but we sold their 127 under the EFKE brand.I could not help but notice that EFKE and Maco/Rollei films in the 127 size had identical plastic spools with a brass insert for the film winder drive, Did Maco/Rollei and EFKE have some kind of cooperative effort going on in the 127 film business?
I cannot comment on Lomo products. I am only comenting on the 127 becaue this is past now and cannot be considered a trade secret anymore.
