bought a rather big aircraft piece which was advertised as being from a me262, I bought it on impulse now I am regretting it

I asked a few aircraft experts around and they said the component could be from the me262 but it is universal piece used on me109 etc so it isin't solely for a me262 so I was kinda "tricked" another thing bugging me is I asked the seller TWICE about if he has any more info or any evidence supporting his claim that it is from indeed an me262 jet but no answer

already paid so I have asked him a question about another item pretending im interested to "catch him out" as he will prob answer me and so I can see that he is deliberatly ignoring my question(s)
reckon it is possible for refund? Ive lost all confidence in this seller
