Identify halberd

The distinction between both raw materials would be that, if being cast iron, a magnet hardly (or doesn't even) sticks to it and you may notice the (sand) casting grain; whether if it is forged iron, the magnet sticks perfectly as you can hardly stick it out, with a smooth face and thinner/sharper edges, and of lighter weight.
The less perfect engraving of the coat of arms would mean that this was not a Kings Guard halberd but a Guard of some important personality, like the Governor of Mozambique or one of the Brazilian States. The shape of the blade, when of the Kings Guards, is rather different, with its two opposite "half moons" as shown in previous post; the Royal crest together with the initials of the King or Regent, are finely engraved, and never of cast iron.
On the other hand, you may not discard the possibility that your halberd was made in the overseas.

Hello Fernando,

Tks for the information, i would check with the magnet but i'am pretty sure it's cast iron and in my opinion i really think it was made in Mozambique.

One interesting thing is the coat of arms, if you notice this coat of arms is not very common, the circular shape can be related with D.Joao VI, i found a similar coat of arms in a canon in the army museum in Lisbon.

Regards,

Looking at this cannon, we notice that the shield is oval, that of Dom João while Prince Regent, as it says in the inscription. Later when he became King (and Emperor) while in Brazil, we see that the Coat of Arms becomes circular, including the armillary sphere. After 1826 it returned to the prior version, as by then Brazil was already independent. In any case, your halberd having the circular shape but not including the armillary sphere, could be due to it not having been made in Brazil but in Mozambique ... i would venture.

It is not cast iron. Cast iron has a carbon content by weight of approximately 2%-4%. As such it is very heavy and rather brittle. It can only be cast and ground. It cannot be holed or hammered (even most makers marks and decoration in cast iron are part of the mold). This piece shows clear evidence of forge work having been done for either it's fitting, manufacture, or both. The work also shows no distinct casting seams or evidence of the removal or wearing down of casting seams.

Neither is it wrought iron. As given it's apparent age and condition we would see at least some evidence of surface cleavage revealing fibrous structure. To me this looks to be a low to medium carbon crucible steel. Worked on a forge from stock. Possibly case hardened.

Hello,

After tests my conclusion ist that it's forged!

About the origin still don't know, asked for "experts" i know opinion and no conclusion.... i will continue to study the halberd, i think the best evidence so far is that ir's origin is from mozambique and probably a local forged one...

Tks.

Best regards,
