  • The type of fuel it uses can also be an indicator; older models tend to run on gasoline, kerosene, or alcohol, while modern versions are more likely to use propane or butane.

Finally, consulting resources such as vintageblowtorches.com, forums dedicated to blow torch collectors, and antique reference books can offer valuable information for identifying and dating antique blow torches. Remember, however, that it can sometimes be difficult to pinpoint an exact age, so focusing on the overall style and design of the blow torch when making an assessment is essential.

6 Factors to Identify & Value Antique Blow Torch

1. Age

One significant factor that impacts the value of antique blow torches is their age. Though older blowtorches may seem inherently more valuable, it’s important to note that rarity plays a more significant role in determining the value of a blowtorch. As a result, some older models might not be as valuable due to being more common in the market.

When examining an antique blowtorch, it’s helpful to know the date of manufacture as this information can help collectors and appraisers determine its age.
