T1 one would make more sense since the coil controlled transistors would only allow for very short spikes(more John-like  . Is T1 exactly like John's cigar-box or could there be missing parts?

Mario,
To the best of my knowledge, Figure T-1, in the Eike Mueller Report is the correct schematic. When I got John's permission to reprint the report in this forum, he gave me the final up-dates to the components list. I stated those component changes in Post #7 of this forum, and I will repeat them here.
"When I spoke to John, he told me that getting the circuit to work is a real pain. The circuit controller must be able to produce a perfect 50%-50% flip-flop. The "cigar box" unit used Ni-Cad batteries, which is why they are labeled as 5 volts (4 x 1.25 volts each). The final working model used the 2N5885 transistor instead of the 2N3055H as listed. The control chip was the SG 3524 instead of the SG 3984 as listed. The system switched slowly, at no more that 20 CPS."
This is as much as I know.
Good luck,
Peter
