Here's a hard to find WW1 French Bertrand gas grenade. Tiny little thing just bigger than a golf ball. As I understand it it contained a glass orb inside it that was filled with gas that was prone to breaking before it was thrown so it wasn't popular with troops.Bought it a few months ago in relic condition & since then It's spent most of its time in white vinegar which is shifting the rust slowly but surely. Seeing some nice grey pig iron as the rust dissolves & I'm changing the vinegar every week or so because it turns black & murky & not so nice. I'm hoping another month will see it back to clean grey pig iron all over. Then its just a case of re wrapping it in some authentic looking wire and job done.
