Talk ‘n’ Action Tender Screws

@TrainsRAwesome Hmm, I'm not sure about this, my Talk N Action Gordon only has 1 screw just like your Henry on the right, I would guess it was changed during the final year they were being produced, maybe a little before, for the purpose of making them easier to be fixed? I'm not an expert so I'll leave it to the likes of Muddy Poppins and others to answer this
