The pickaxe lapel pin has a tiny engraved sterling silver plate that states: NorvalsPont May 1900. After many hours researching, I know that Norvalspont was a concentration camp in May 1900. The only railway bridge leading in and out of the community was destroyed during a conflict. I am curious to see if these where made for the men who worked to reconstruct the railway bridge, or if the pickaxe was for a job completed. My personal opinion as to why the lapel/tie pin was created was to commerate a small victory or to mark a historical event at this small village & concentration camp in Norvalspont aka The Orange River Colony. I have made contact with a gentleman from Norvalspont, South Africa. His last name is Norval as well. He was in his exact words, "so jealous he could just spit" when I sent him photographs of this little treasure I found at a flea market in the state of Georgia in the USA. It has a history behind it that means a great deal to the local people in Norvalspont. I hope I can receive some answers so that I may share them with my new friends in South Africa.
