I have an old fretless, 5-string, having a 27.5 scale with 17 flush (inlaid) frets and a 13-inch diameter pot. Having done research, but still confused, bear with my questions.

Historically, what does this this banjo scale mean relative to banjo history, why this scale  and limited number of frets? Is this a common scale for minstrel banjos and why?

Could you please share some photos of the banjo? That way I can tell you more about it and address your question.

If you're talking about what I think of as "minstrel era" (pre~1870), extensive fingering above the 12th fret was pretty high-level virtuoso technique. 17 frets wouldn't have been considered limiting.

Measurements weren't standardized then. Scale lengths were all over the place. 27.5" seems pretty average to me. It's still within the range of what's considered a standard modern banjo scale.

VERY generally, it's often true that larger pot diameter banjos have longer scales. I suppose for volume in per-microphone days. So a 13" pot, which is on the larger side, would tend to have a longer scale -- 27.5" is on the slightly long side, but not at all unusual. Vega/Fairbanks banjos with around 12" pots had 28" scales (with complete set of frets) for fine "classic" playing. 27" scale on 11" better model banjos. But there were no hard and fast rules on scales, nor "standardization" like you see today.

Long scale is the term.

There's really no such thing as a minstrel banjo. There are banjos, and then there are banjos. Some were played by professional minstrels, and some weren't. Minstrelsy peaked in popularity during the 1880s, and a banjo from that decade that was played by a minstrel isn't any less a minstrel banjo than one from the 1850s.



By the 1870s, banjos with 12" pots were starting to become the norm for professionals, although some players still played larger instruments. Scale lengths continued to vary for most of the decade, although many professional instruments had long scales (28" and longer). 27.5" on a 13" pot is not long - in fact, it is quite short for a pot that large, although not unheard of. In the 1840s - 1860s, banjos were were more variable in specifications Without. Without photos however I can't tell you what you've got.

Scale length affects where the bridge is located on the rim and hence the tone.

Choose an ideal bridge placement, for argument sake lets say at the the third point of the rim. (one third of the diameter from the tailpiece). An 11" pot with 27" scale neck will put the bridge at or near the third point. If the rim is increased to 12'' the same 27" scale neck will place the bridge closer to the mid-point of the pot, simply because the pot is bigger. The bridge is not sitting at our "ideal" third point, thus altering the tone. To get the bridge on the third point of the 12" rim, you need a longer scale. With a 27 1/2" scale and the bridge properly placed, it is closer to the third point, but not quite there. A 28" scale with 12" rim places the bridge pretty much at the third point of the rim.

The same principle applies to any "Ideal' bridge location. Many clawhammer players prefer the bridge near the mid point of the rim for the boomy tone. This allows for slightly shorter scale lengths. For an 11'' pot, a 25" scale will place the bridge close to the rim midpoint. For a 12" pot the scale length increases by about 1/2" to get the bridge near the center of the bigger pot.
