Sorry to hear this. We used to use Balcar units in the studio in Chicago in the 70's and 80's. We purchased from their salesman, Ken Lerner I think his name was. Later, Ken went on to Speedotron and I also saw him at Calumet in Chicago. Nice guy who told it like it was. I still cherish my Balcar umbrella. I have a white one with the black back. I never bought the diffuser front for it. The owner, Denis Scott, used one though on his setups. I shot models in B&W in our studio downtime. I made wonderful 11x 14 B&W prints for model portfolios using Hasselblad and 35mm. We emulated Avedon, Skrebneski and Scuvullo and tried to match their B&W quality. Those were great times for me and I totally miss it. My head is screwed on wrong now, trying to relive those times using what attainment I already achieved in those days but in the eternal right now.
