Please help on bronze axes

Hi Fernando,
It seems the story hasn't ended

I've been thinking about the regular markings......

IMHO The marks on the axehead, suggest a single 'punch' with a very small rectangular end was used. Although they are almost arranged in a side by side configuration, in two parallel rows, it looks as if, each mark was done individually.

Notice how some are 'deeper', suggesting a harder strike on the punch. Sometimes the 'twin' of some of the marks are missing. Some of the marks appear to be struck from slightly different angles. Although fairly evenly spaced they are not 'exact'. Also noticeable is the fact that these marks occured after the hammer finish ...some 'cut' into the 'peaks' of the hammer marks.
Hopefully, the enlargement of Fernando's picture will explain better.

The other with the yellow oval, highlights an area which seems to be 'later' damage....its surface is 'different' to the rest of the 'hammered' surface and some of the 'notch' marks seem to have been deformed by the 'impact damage'

Regards David

Thank you David,
So we can take fore sure that these marks were not the result of casting ... be it either ancient or contemporaneous.
The pictures attached are as afar as i can go with my digital camera; close ups not closer than four inches ... it is an "old" pioneer.
Take a better look to the wavy pairs.
I have found meanwhile another set of marks ... on the same side of the axe edge; also with a bizarre look.

Let's suppose these are modern-made... Perhaps those punch marks are the result of toothed tongs used to hold the pieces while they were dipped in some acidic solution to artificially age them, or to remove them from said solution.
In either case, the marks are irregular enough to have been accidentally made. I don't think hammer blows would reproduce the relatively precise alignment of these marks.

These axes make for a nice little mystery, Fernando, regardless of authenticity.

I don't think bronze is so soft as letting simple toothed tongs impress it so deeply, just by holding it.
Also dificult to be hammer marks, as they have more than one defined pattern.

You're dead right, Emanuel

I do agree that on close inspection the parallel marks seem to be made with a single punch, which makes it difficult to imagine that they are an unintended by-product of the manufacturing process (like the grind marks). Asuming the punch marks were not made by a modern vise, clamps, or whatever, why would they have been made originally? They appear too random and inconspicuous to be decoration. Yet, it would have taken a great deal of attention and precision to punch in the marks in such a regular pattern. Some sort of tally, maybe? I just can't think of why they would have been put there.

I've tried to enhance/enlarge the latest pictures Fernando has uploaded.... very strange. The 'pattern' within the 'marked oval' seems very unusual ... perhaps someone may have some ideas ......

being an avid CSI fan, i suspect that someone here either is or knows someone who is a CSI or forensic lab tech. they generally have tool mark libraries for finding out what tools may have been involved in crimes, they may recognise or be able to look up the tool marks.

my initial thought was they were vice jaw marks which may have been added by some bright spark recently (last century or so

)
