Info requested - Yardsale Rollfast

[Sven]

I bought this Rollfast at Virginia's 100 mile yard sale. I know the wheel and tire set are from ,what I believe a Schwinn Tornado. The seat is a Brooks. Other than that..I know nothing about Rollfast bicycles.
Tried to find information on the serial numbering on Rollfast. Some say it doesn't exist.
Requesting model and year..

B291867
Thanks in advance.

The “SE” is for Snyder Enterprises, (formerly Snyder Manufacturing); not sure when (in the late 1950’s) that change occurred. The letter “B” may indicate a year and the six digits just a sequential serial number.
I believe that a member @Adamtinkerer may have worked at reverse engineering a rule to decipher the code for circle-SE stamped bicycles.

I found this just looking around ..

If this be the case A= 1959 ; B= 1960 .....F=1964
Does that sounds right to you?

Tire/wheel set would be from a Schwinn Middleweight (Typhoon, etc.) if the Times are stamped "Schwinn Tubular S-7" and the tires are 26 x 1-3/4, not 26 x 1.75

Correct!
The tires are Schwinn "Westwind" ,
"26 x 1 3/4 TO FIT SCHWINN TUBULAR S-7 RIMS"
Schwinn Approved hubs are made in Germany .
And the Rims are ivory in color.

B = 1960
