I live in Mozambique and found this on the side of the road where it was waiting for a truck to take it to Beira where it would have been loaded on a ship to China to be turned into rebar. At about US$0.20 per pound the seller was grinning from ear to ear, not believing his luck in making so much money off this crazy umlungu (white man)! Needless to say he is now busy sniffing out any further such items for me!
I can only assume that this is from the Portuguese colonial era which came to an end here about 50 years ago, and with a scrap metal industry beginning to take form here, all types of unused metal goods are being sold off to the smelters in the Far East.
I'm estimating 65kg, will weigh it after I've separated it from its base. 62cm total length, 13cm wide face, 26cm tall. I cannot ascertain any markings on it, other than on a plate fastened to the side, bearing the words "Fajten URSS", and a sequence of numbers below that - possibly weight, date etc. designations?
Maybe someone here has some idea on its origins?
