Value of Springfield 1911 A1 pland Jane GI model

[762shooter]

A friend of mine wants to sell the above pistol but has no idea what its worth and I'm not sure either. Can anyone help me out regarding its realistic value? It is bone stock, 45 ACP, about 10 or 12 years old, not used too much, very good condition.

Thanks for your help!

Probably 550-600 I would guess.
