https://www.jfkassassinationforum.com/index.php/topic,2862.0.htmlHere is in effect Towner frame T138, which is missing in Robin Unger's gallery. He shows T137 T139 T141 T142.
T138 & T140 are missing. And T143 never happened -- the last frame was T142 (i think).
So, here below is in effect frame T138, a printscreen from i think the Museum's online Tina footage.
Oswald's shot-1 was at Z112, say T137.
Slug hit signal arm (& fragments hit JFK) at Z113, say T138.
We know that Z113 was at T138 koz Nellie Connally is level with the end of the white painted road stripe, in the re-enactment footage, & in Tina's footage. Sound hit Tina at Z114, say T139.
Tina hears bang at say T141.
Tina possibly had a non-voluntary startle reaction to the bang at say T143 (except that she stopped filming at T142).
Tina possibly had a voluntary fright reaction to the bang at say T145.

Here below are some more printscreens.
