Need an old style harpoon

Hi there Cubers. I'm currently working on a production that I will need an old style harpoon. Something like the one in this photos attached. There was one at ABC but it wasn't available when I went to pick it up. I've also looked into other prop housed and not luck. It's a really love budget film so buying one doesn't seem like an option. It doesn't have to resemble exactly what's in the photos. We just need it to not look so modern. Let me know if anyone has any insights. Best, Celina
