| This is a Nesco 4215 heater with a font that is dated 1948. My wife bought this to use as a plant stand. I eventually started playing around with it and figured out how it worked. That lead me to research it and discover the Perfection line of heaters. |

| This is a Perfection 525 heater. Although the font that came with this heater was not made of brass, it was the older style font with a dial for the kerosene level instead of a float. That font was rusted out though and was replaced with a newer style one. |

| This is a Perfection 525M heater. It is a updated version of the 525. It's possible that the M just means modern. The 525M doesn't have the window that the 525 does and the body doesn't have the ridges is it. The airholes are also different in the 525M. I'm sure this simplified the manufacturing process while retaining the vintage feel of the 525. |

| This is a Perfection 725 heater. This is one of their modern heaters that still has the window in the side. This particular hearter was refurbished before I bought it, but the person refurbishing it didn't use high temperature paint. This will lead to the paint outgassing so I'm only going to burn it outside until I can strip and repaint it. |

| This is a Perfection 730 heater. This is one of their modern heaters and appears to be the version of the 725 that doesn't have the window in the side. The logo on this heater doesn't have the model number on it, but I have another 730 in worse condition that I will be switching the logos on. |

| This is a Perfection 735 heater. It is one of the Firelight models. This is the first kerosene heater that I have refurbished. I soaked the metal parts in Evaporust and then a citric acid solution. The last step was to treat it with a tannin solution. |

| This is a Perfection 750 heater. It is one of the Firelight models. The best I can tell, the only difference between the 735 and 750 is that the 750 has a ridge in the metal just above the glass. This 750 also appears to have a porcelain enamel finish. |
