Just picked up a wooden coffin smoothing plane and am curious about an 
approximate age

Body is stamped
D. GALLOWAY & CO,
EDINBURCH

above a two headed winged beast behind a shield above
D. MALLOCH&SON,
PERTH

Capiron is also stamped D. MALLOCH&SON.

Blade is marked THOs IBBOTSON&Co.


Also, what is a good reference for looking up this sort of information?

Thanks
Ken
