The signage on the door says it all, “Rock Wool Fibre Glass Shavings.” Sounds like a good recipe for an itch that’ll be impossible to scratch. The actual business this truck was employed under is about as mysterious as its lineage. From what we can tell, it’s definitely an early ’30s model. However, we can’t put our finger on the origin of that grille, but it is very cool. Nonetheless, it looks like it’s been put out to pasture after serving many years as a helpful hauler.
