Original 1952-1954 Fender Telecaster Serial #1424
If it's legit, it's definitely a '51. Obvious from the specs anyhow, but the serial number says for sure.
A '51 Nocaster is one of the holy grails of Fender guitars. It's worth a lot of money. Not house money, like an old Les Paul, but definitely really nice car money. It's worth about twice what a blackguard Telecaster is worth, due to it's relative rarity, desirability, and historical significance. The only possibility-more-desirable standard production Fender from that period would be a Broadcaster (same guitar as yours, but before Fender got a cease and desist notice for their use of that model name).
I'm sorry for your loss. Now sell that puppy, and do what yer pops would want you to do with the money, without thinking twice about it.
