Help finding a watch case!

Hi all I’m hoping someone might be able to help point me in the right direction (fingers crossed!)

I’m a complete novice who is just starting to get into watch repair. I’ve bought a speedmaster cal 1152 to work towards and I wanted to find parts to have ready, but I can’t seem to find any previous sales of a case! I believe the part number is 175.0043 and understand genuine parts will be hard to find so I’m also open to third party versions too (I’m not looking to sell it on afterwards) Is anyone able to share any tips of where to look with links if possible?

Any help or advice is greatly appreciated 🙂

Cases come up on ebay. Also in this forum, in the appropriate subforum. Outside of that, you would need some sort of connection with someone with a stash, or that might end up with an old case here and there.

Thank you I’ll have a look over the subforums & I’ve saved a couple of searches on eBay here’s hoping something comes up!
