I'm not sure but the revolver on the first screenshot seems to have shorter barrel than Mk VI and lacks the typical large front sight. Nevertheless the shape of the grip is Mk VI-style and differs from pre-Mk VI .455 revolvers, except maybe for Mk I. So this is a tricky issue. --Greg-Z (talk) 11:55, 8 September 2020 (EDT)
The position of fingers make me think about "bird beak" style grip... but it's so vague that I wouldn't state it as proved. Maybe it would be better to just note in the description that this particular revolver has a barrel shorter than standard Mk VI due to unknown reason. Sorry, no better guess. --Greg-Z (talk) 02:13, 9 September 2020 (EDT)
