Seeing post number 7 reminded me of a company I worked for many many moons ago now long since defunct (Transdata Ltd). They had bought in a couple to "have a look at" if you know what I mean! They (within about 3-4 months I believe) came up with their own version namely the 307 & 307A acoustic couplers. Both very good in their own right (up to 300bd), we sold thousands of the things, mainly to the GPO! I remember testing 30-50 a day & then on Fridays sitting down with the duff ones & fixing them. I always thought the GPO one was far better built, it just looked right.
