Hello - Newbie here!

Hello...
I`ve just taken over my dad-in-law`s 1948 Type "M" lathe which he doesn`t use any more.
Mechanically it`s in pretty good order although it`s really dirty and full of black sticky gunge around the change wheels. It`s fitted with the tumbler reversing gear which is handy to have.
I need to give it a good clean and see if anything needs fixing.
Cheers
Malc
