I have a rifle of someone famous (in the gun world), but I could never bring myself to ask him what amounted to... "Could you write me a letter so when you die my gun will be worth more?"
I always ask for a letter.
Ask.
Don’t look at it as a negative, but as a positive to give credit.
I would gladly give you a letter if I was the famous dude.
Famous dude may feel the same.
