The Type 75 is a nice truck if it is powered by the ENF510A engine, a six cylinder overhead valve engine. It is the most powerful engine they used in those days. Prices of antique fire apparatus is really driven by rarity, completeness, and condition. The Type 75's were the second highest production run of the E models with 393 built, so they are not all that rare. However, if it is a crew cab it is much rarer and worth more. Condition is hard to tell from pictures, but I would put it at about 3 to 5 out of 10. It lacks gold leaf, a bell, and the paint looks rough. A bell will run you anywhere from $500 to $1K. Real gold leaf will go north of $5K; paint anywhere from $5K to 20K. It appears the ladders and hard sleeves are missing, as well as most of the small tools. All of these can be easily found and should run you less than $1K. If it runs correctly and it is a crew cab I would be comfortable paying $3K and if I really fell in love with it I would go the $5K. Just remember owning antique fire trucks are like owning a boat. No reasonable person ever bought a boat and planned on getting his money back, and you will not make money with this either. Buy it because you like it, want to have fun with it, and are willing to preserve it for the next generation, not as an investment. Lastly, any antique fire truck must be kept indoors. if you do not have indoor storage do us all a favor and walk away so it doesn't die a slow undignified death rusting away in a back yard.
