do you like this model better
I guess that wasn't really very helpful.
I have done this before but maybe it was a long time ago and it's time again.
these catalogs were not for consumer eyes, they were for prospective wholesale buyers. Say you were a Mom and Pop grocery store, and you wanted to sell a few bikes because the nearest Sears catalog store was in the next town over. what do you do? you contact one of the bicycle manufacturers and they send out a salesman who drives around his area to various stores selling the Brand X line. when he gets there he shows you this catalog and asks you what you think you could sell, and makes suggestions based on this catalog.
now lets get a bit more specific. say the salesman comes by and Pop says "Boy! I sure like the look of the Top Flite line but they are just too expensive, what can we do? the salesman pulls out a couple sheets of paper like these.
the salesman says, that's no problem, why don't you order the Model 31 which is cheaper and we'll add a few of the nicer parts, like the deluxe fenders and lit rack. "Giant Balloon Enamel "A" decoration fenders are only $0.35 more per bike! the kick stand instead of the drop stand is only $0.20, and the lit rack is only $0.90! since the Model 31 is cheaper, you'll save a bit on every bike! so Pop orders his 10 bikes for that year model, and they're slightly different from any others because no one uses these "Confidential Cost Sheets" exactly the same every time, and the sales man is on commission so he does whatever it takes to get Pop to buy a few bikes.
of course this is all speculation but these price adjustment sheets are real, and the bike looks authentic, and it doesn't really fit the catalog very well, and it's all we have to go on.
