Hi Günther,
Yes, Mr. Walter needed to have other product lines to sell to help with revenue including the Triax unit.
We certainly saw what happened during the later MW years with the lack of needed funding. Mr. Walter could not even pay Mr. Birett the money that was owed for the Funktionsmodelle model development and had to given him an XY plotter to settle the account.
I still believe that were it not for Mssrs. Schrank-Von Seelen-Kopperschmidt, the Lectron System would have passed into oblivion back in 2001.
Best,
Michael
