Hi Stig,
I did consider TL+HT, but Stammkennzeichen.de has it as a Bf 108 B-1 recorded with several units. Like yourself I'd seen the TI+HT used in conjunction with the Fi 167 V1 in among other sources German Secret Flight Test Centres (I should have put Travemünde not Rechlin though - bad record keeping on my part).I the went to:
https://web.archive.org/web/20140508...rg/stam-t.html
which does have both the Fi 167 and Gotha Go 145 under TI+HT and the latter is marked under photographic evidence with a 'green rectangle'. Also,as you'll be aware both TI+HU and TI+HV are jnown to be Go 145. So, like yourself, I'm open to corrections
, but for the moment sticking with TI+HT as being the Stkz shown.
Regards,
Clint
