geometric design on lead bar

[mtholen]

Found this at a house built in the 40s. It is lead and has a pattern on it. It is broken and had to use an old Mason jar lid as size reference.

Looks like lead "finger bar.
Sold like this for those who used lead.
Just a guess... not sure about marks.

Imprint from plaster lath diamond wire.

If you look at the marks, they are equal measurements. Notice where the Lead was cut, on the line. Not sure what these small bits were then melted down & used for but maybe 2 musket balls worth??
