If the town or the fire dept cared they would have NOT left it in a field to rot away for 30 years. Fire trucks do not cost more to restore than any other truck, if all the lights and siren have not been stolen. A siren can cost 300 to 500 for a good one. If it does not run and no brakes it is probably worth more as scrap that as a truck with current prices. Also is the body part of the cab or could the body be removed and the truck rebuilt as something else? They are getting more popular as you will find them with very low miles, garage kept and are not beat to death and worn like most old trucks you will find parked behind some barn. My Fire truck is a 1959 international and has less than 9000 miles on it. Just broke in. I would pass if strings are attached, sounds like they want you to do all the work for them. Check out your local craigs list or e-bay, you would be surprised what you can buy a running driveable fire truck for. Good luck. Bill
