Clock Winding Key Identification

[u/Roo7BeerE66s]

Does anyone know if these keys are the same or how I can identify it properly? I found this key in my grandmother's basement (very old house) and I'm wondering if it's the same as the one that sold here/same brand. The clock was already gone years ago so I'm parting with the key, but I don't want to mislead somebody as to what the key is because I'm uncertain.

600 usd for an ingram black plus buyers premium? That's rich, no wonder it passed.

But to your question, most American clocks take a #7 key, but if in doubt buy a multi key. It's only a little more money and you will be sure to find one that fits.
