Never mind Fernando, we all have to take risks now and again ....when trying to obtain unusual or rare examples of weapons, when they 'pay off' ....

......when they don't ....well, you get the picture

I would have been very pleased for you , had these been genuine. Still, I have learned alot, also thanks Kronckew, I had assumed that the sprue (normally removed) was left on some axeheads (ie a 'longer sprue' which would have been ground down to remove the 'imperfect' bronze from the upper section) for use as a hammer/chisel head and therefore the quality of the bronze would be consistent.
Sometimes lateral thinking can open up new possibillities....in this case, it lead me astray
