I hope so. She gave me a chart and it's pretty much in line with what Bourns offers for straight B taper.

If you look at their PTL and PTA datasheets, Bourns has a taper chart, but nothing in the PTB datasheet. It took Bourns something like 2 weeks to send me that chart.

By the way, I was in talks with one manufacturer that identified their slide pots by PTB. I didn't go with that one; their price was just a bit higher than "the chosen one".
