Hi All, I'm new to the site, have been collecting stoves for a few months, like to use in the field on a forage, hopelessly nostalgic for times past and just love the simple but amazing technology that converts liquid to gas! So I have a No. 96 from 1916, lovely looking but vaporiser hole is blocked and may need drilling out, cannot be pricked. Can anyone advise on size of drill bit and if it's possible to procure such a small bit? I don't think I will use this in the field but would love to get it going and know that it's functioning. Any help appreciated, thanks.
