I was sent this photo the other week from someone who had removed these Max Howden crystals from an old radio. An Interesting crystal holder, Max ran this company in the 1970’s and his son continued the business into the 1980’s I’m informed. Another piece of the A3BQ / VK3BQ callsign history.
I used to order crystals from MH for my Tandy Electronics Realistic 4 Channel Scanner. You had to be sure of the frequencies you wanted as there was no “reprogramming”.
Thanks. I’ll have to get some in a holder as a souvenir
