Frame Tank Question
 

Well I've got some pictures of the Columbia bicycle- it's a very nice medium blue color with white-cream trim. However the tank that came with it appears to be a slightly different color. The bicycle is a 1950 Three Star Deluxe, but I'm not sure what year or bicycle the tank is from. It is differently from the "round" tanks I've seen- this one has sort of a geometric kind of design to it- it's all flat edges. Does anyone have any ideas about this tank?

Also a matter of raw opinion- is the color difference great enough to warrant keeping it off the bike? I am having a hard time deciding if the tank is just too different to put on or not- any opinions or advice are much appreciated there.

Maybe the tank is from a green bike? Similar to a prewar Rollfast I have, shape looks appropriate. There are other baloon tire sites that may be of more help, but I'm not sure what they are any more.

Update: progress on the bike includes some new parts; frame tank is off for now.
