I have a clear recollection of Lowe writing a letter to the Model Engineer magazine in the 1950s, but I have been unable to find it. My own collection of Model Engineer magazines (though substantial) has a few gaps, and the online index hasn't helped, but I did have access many years ago to bound volumes of the Model Engineer magazine.
Incidentally, Boxhall was also someone who read the Model Engineer magazine, though he probably read it in his local library rather than buy it!
Incidentally again, Leslie Harrison, in Titanic Myth Part 2, refers to Boxhall applying to the MMSA for financial help.
Cheers,
Julian
