Lee Melter furnace dimensions

[Love Life]

This is kind of an odd one, but does anybody know the depth of the lee melter furnace, and the width across the opening? It's the 4 lb model.

I'm looking for a pot to Nitre blue parts, and just want to make sure it'll fit a 1911 extractor in it.

Thank you!
