Jerry,
It was once my understanding (don't shoot me if it was
incorrect) that Reynolds 631 was the same material -
metalurgically - as 753. The difference was that 631 was not
subjected to the same heat treatment as 753.
Since I've also read that 753 was the same basic material as
531, does this mean that 631 was simply 531 in thinner gauges?
The current Bob Jackson Web site describes 631 as the same
material as _853_ but without the heat treatment. Does that
mean that the current 631 is different than the original 631?
Or does it mean that 853, 753, 631, 531, etc. is whatever
Reynolds wants it to be during any particular era?
That is, at this point, Reynolds might well consider this
numerical type-designation to be a marketing tool and - as long
as the frame is well built and light - the buyer will never be
able to distinguish between subtle metalurgical differences.
Cheers,
Fred Rednor - not yet being subjected to heat
treatment in Arlington, Virginia (USA)
