Sadly, like a few other threads, I seem to have left the latter unfinished.
Note 'I'll do the promised 3-way shot another time'. I didn't say when. In fact I'd since acquired another Racer J39723-70 in August 2020, in gunmetal finish with a white dial, which I wrote up on page 7 of the Spanish Inquisition thread. Most likely reason I didn't take any more group shots at the time is that I'd remembered the J39723-70 isn't particularly easy to photograph (minor understatement), due to the reflections from its domed flat-bottom crystal.
