Your x53 is a 1956 paint is black cherry and gold.They also had a red and gold.1957-58 were black and gold
My X-53 which I got for Christmas of '54 came in an
irridescent dark cherry. The only difference was the
gold parts were chrome. Other than that, the bike looked
exactly like yours. The bike came from the Western-Auto
store unassembled in a carton.
Don't recall what happened to the bike.
I since found one in an old bike shop.
Colors were faded, but it was all there
including the beefy rocket headlight.
Not sure what color to use to get that
shimmering, metallic or flourescent red.
I also have a red phantom from that year
with that type of "red" color scheme.
Congratulations on your bike.
Don't see too many of these beauties anymore!
