Keys 441 - 444 Belts, Candelabra, and other Sources
Key 442: the rings on this key are from a belt and yes that's an owl (he's missing an eye or if you like you can pretend he's winking at you) at the end on the other side.
Key 443: the rings on this key are also from a belt. The end "lock" bit is the bottom of a crucifix necklace that had two roses that I used in Key 437 and also a skull that I threw out (because I'm not into skulls and I don't spend time with bits I don't like).
Key 444: has a bit of old broach on the bottom end and pieces from a candelabra on each side of the top end - I love how these flowery bits have the silver worn off - surprisingly there was no candle wax on these bits even though their job was to catch the drips.
