Sorry for the crummy pictures. A little shakey today.
There don't appear to be any repairs to the trigger guard, and no soldering. Just my inept photography.
I've never removed the lock plate, but could I guess. It does read "London Warranted".
It's a half-stock, octagon to round barrel, with fixed sights, and a single (and never repaired, as far as I can see) trigger.
Thanks for the feedback. I've spent HOURS trying to come up with info, to no avail. You guys are a great help!
