This out-of-the-way church has managed to hang on to a lovely Walker with GG manual and GG pulldown pedalboard. The pedals and the gaps between them are so small, I'm told this is common for pull-downs on chamber organs like this, but how would one have played them with any comfort?! The pedals seem to be barely 2cm wide, with gaps of a similar width.
