Brass Bohemian Haquebut 1440

Hello Marcus
Merry Christmas and congratulations to your new barrel

If you have a possibility to X-ray the barrel, the lead ball should clearly be visible. There you can also determine the volume of the powder load.

Hi Marcus,
I see that your beautiful brass barrel doesn't match with the others of your collection.
In case you regret having acquired it, let it come over Portugal and i will take care of its unloading .

Thank you and a happy new year to you That is a great idea, will need to search for someone who could do that for me, maybe the dentist.. though it would be strange to carry this to him.

I know you would surely pay the price for the Brass, but i don't want to burden you with this "corroded" piece.. it would need to be cleaned to bare metal before it would be worth anything, i am sure :P

Hello Marcus
I fear that dental X-ray machines are not powerful enough for X-raying metal objects. Probably it may work with a powerful medical X-ray machine on a high output capacity and a long exposure time - bus this will need a lot of experience matching the right settings. Definitively it should work with an unit for Non Destructive Testing.

Hi Andi,

Do you know anyone who is capable of this? In the Netherlands these machines are only found in hospitals and i can't bring myself to go there with a antique gun...

Maybe in a technical universities, a steel processing company building high pressure pipes or equipment e.g. for gass pipelines or nuclear power plants, or companies providing Non Destructive Testing services....

Why not bringing it self to the hospital just strap it around your leg with palster bandages and tell the doctors your leg might be broken

Well there is an idea

Something else though, i just watched the surface under a microscope to identify the blackish surface and the red/orange dots. At first i though the later was some sort of paint because it looks like some sort of banded patern at the socket area, but both the black as the orange might be some type of oxidation.
Would this be possible for any brass composite? Lead, or any other added metals inside the brass?

Edit: it might be a coating of red lead/ minium.

Very similar brass haquebuts guns in the Stockholm museum. No measurements given, but the smallest one seems of almost equal design as my bohemian cannon.
