Question on '74 P bass neck

[Alexis Duntov]

So my favorite bass is my '74 Precision (pictured below). Does anyone know the window for this neck profile? At some point it changed in the 60's from a flatter shape to a chunkier one. The radius may also have changed. I'm trying to identify the start and end dates for this shape. I understand there may be subtle variations in each neck, even between instruments made in the same year, but it's this general shape that I'm interested in. I want to get a backup that feels close to this bass. I played one yesterday that I believe was a 1976 and it felt pretty close. Different logo of course, but overall pretty similar. Eager to hear from others. Thanks.

They changed the neck sizes in 69 , around the time they started using the larger tv logo .

Cool, thanks. I think '75 may have been the last year of the TV logo. I had a '75 once with a nice fat neck but it weighed a ton. My '74 is about 9.5 lbs and manageable.

The "B" width was chunky from '70 right up to '83.

The bolder black Fender logo began in 1968 and continued through the end of CBS production in 1983. The chart below from a Bass Player article discusses the evolution of Fender P Bass neck profiles between the 50s through the 70s.
