Well, I found this: https://www.monoandstereo.com/2015/0...lug-horns.html
Yeah, certainly not up to the tin knocker's workmanship, but if viewed from the fact that the horns were originally designed to get 12.5 kHz out of a ~7 kHz driver whereas nowadays the 288 and similar easily go out to 12.5 - 15 kHz, so throat 'finish' isn't so critical unless your hearing is good enough to perceive a dog whistle, hence the minor ripples in the extreme HF of these tiny edge mismatches.

'Been there, done that' 'chasing' the last bit of smoothness out of a pair of 511/802 only to find that I couldn't perceive any improvement in the extreme HF (really worth the effort down lower though!)
and the females I used for this BW claimed it just made the recordings sound too shrill/dissident to the point where I had to roll off the 1.6 kHz EQ slider all the way down (-16 dB IIRC).
