Post War BSA S rehash

[slow_runner]

Locked down, captive in my home.

I was giving my air rifles a wax prior to the Winter settling in.

A few years back when this BSA was put back to use, I had considered replacing the trigger block but sense and a lack of opportunity prevailed. I left it as it is.
It is bugging me now and the idea of cleaning it up has resurfaced.
Thinking aloud-
I could turn it, although that would obviously reduce the diameter and lose its identity number.
I could dress the damaged region? Nah, maybe not a good idea.
I could have it micro welded; less heat and that would be labour intensive and expensive.
Tig welding may be more affordable but that generates some heat and would need a number of passes to reduce any possible distortion.
Then there is the reblueing and would the weld zone material colour well with the original material?
Or leave well enough alone?

Has anyone recovered a similarly corroded trigger block with success and how was this achieved?
Any advice?

The damage can be seen here.
