I have to say that the post below from a few days ago has a number of assertions that are questionable.
Quickly measuring the 10 or so Brooks B-15s, B-17s, Pros and Swallows that I have, the average leather thickness at the flaps is typically 5mm plus or minus .5mm. Of the three B-15s in the sample, none are thinner than the average and in fact, the thickest leather on a Brooks saddle I own is a B-15 at about 5.8mm.
As to quality I have one B-17 Champion Narrow that is at 5.5mm on the right flap and 4.5mm at the left. Guess what- this 1964 saddle is pretty crooked over the years.
None of my B-15s have an under patch. I have a Lycette Swallow with an under patch but it has 5mm "flaps" too.
Also the B-15s and Swallows are not chamfered.
I agree about the steel rivets.
It also seems to me that many Schwinns (Sport Tourers and Super Sports) came with B-15s well after 1971. Of course Schwinn may have held a large inventory. Who knows how many sets of Nervex lugs they bought in advance of their immediate needs.
Maybe the B-15 was intended as an OEM variant? Does anyone on the list remember buying one new that wasn't part of a bike?
After all that, and all those Brooks saddles I seem to own, I am still not a Brooks aficianado and Ideale has never worked for me at all. I am coming to realize that the Narrows and especially the Swallows fit me better. On the other hand, Larry Strung has a 50's Brooks sprinting saddle so narrow that it only fits, as the Vermonters say, where the sun don't shine.
