They are very unique keys. They are also hard to find. I don’t know the story of Helason keys and locks, and even if they are still being manufactured, but I do know they have an Austrian patent (it says so right on the key. You can’t miss it).
I never get eBay notifications of one listed on auction, but then one day I did. And it was for three keys. Wow! There were already a few bids on them but we were at $5. I had no idea how much they’d go for but I was willing to pay a little bit.
I won them at a little above $8, and with shipping from Canada it came to about $13. So worth it.
They arrived in their natural state of tarnished brass. Many would say I should leave them as is, keep them authentic. I say shine ’em up, baby. I want them to sparkle. So I polished them with a concoction made up of vinegar, baking soda, and salt. Aren’t they beautiful?
They’ll tarnish again over time anyway. What am I going to do with them? I don’t know. I’ll do something with them, but right now I don’t care. They’re in my possession and that’s all that matters.
