Hi
To Captain Uri Askenazy
In Appeeciation
From the chief and crew of the vehicle workshop
December 12 1968
It was once very popular to give such works of art as an unofficial tokens of appreciation made from ammunition and gun parts.
In this case it's a part of something called Channokiya (I hope I spelled it right) used to light candles in the Channuka.
Every house had such things when I was a child.
Hope this helps
