Hi John I can match your Silver Streak ( three times lol ) and up the ante with both Red and Blue Golden Eagle versions . as well as the Brimtoy( Wells) Silverlink set
In good condition ...
Annnnd not so good
And full rake for the red set ...
But sadly I have bad news for you regarding the Mickey Mouse status of your loco ... although basically the same mechanics and body shell shape the Mickey Set had a slightly different lithography with red and black accents , Dual cab window cut-outs , real wire boiler handrail ( litho on non-Mickey sets) and red siderods ..
