This Cox Golden Bee .049 was purchased on eBay for around $30. It was very dirty, but disassembling it and soaking it overnight in a bath of
Evapo-Rust worked a miracle on it. The shiny metal parts were buffed using a Dremel MotoTool.
Here is a photo of how it looks disassembled - after cleaning. The cylinder could stand to be re-anodized with a deep black, but that can come later. For now, it is sitting as a display model, but eventually it will be installed in a display model of the Carl Goldberg
1/2A Skylane.

These gems are no longer produced, and getting hold of one - especially with the original package - is costly if you shop on eBay. They regularly sell for $100 or more.
