Hi Michael,
Thank you, i will investigate
M Eley, could the grenade of yours be some sort of post medievalish molotov cocktail? In Michael's thread about incendiaries, there is also a part about incendiary quoites which probably would have splashed around when lit and cause flesh melting burns
Though the quoites are solid, i am sure that there is also a liquid exuivalent (maybe just oil/tar with sulphur)? pure guess work of course
