HW77 / K MK1. Ser no.

[Mach 1.5]

Anyone have a rough idea at what serial number the Mk1 77 was finished and the MK2 started? Mach 1.5

AFAIK HW77 MK1 was produced from 1980 - ser.no. 843636 until 1984 / 1985 so about up to ser. no. 102****.
If it's a MK1 77 it will only have two scope arrestor holes in the back block and no anti beartrap mechanism.

MK2 with thumb sliding underlever catch.

Not trying to hijack but what if it has 2 scope arrestor holes in the back block and no anti bear trap but also a sliding thumb catch for underlever release?

I wonder if there was a slight crossover 'twixt some of the component specification?

Or if the Mk1 catch had been damaged and replaced with the Mark2 part (assuming it fits)?
