Arran, as far as that choke in series with the antenna input, you can just jump it out. It was part of a wave trap ( with a mica trimmer ) tuned to the 260 KHz IF freq.
Back when the radio was made there was a lot of communications activity on those low freqs and sometimes a strong enough signal would bleed into the IF causing interference. Today, that LF band is pretty dead so the trap is no longer needed.
