Peter,
I've only learned to copy and paste, not post originals, but, there's still hope that an old dog can learn new tricks.
Jim,
The resemblance, especially with the schematic, is stunning.
If Colt had played the original Biarritz, or even if he just viewed it in person, the terrain at the 5th at PV had to scream out, "Biarritz"
to him.
While the elevation differential may not be what Yale's is, or what George Bahto indicates the original Biarritz was, the opportunity and resemblance is uncanny.
Did Colt write about the creation of # 5 at PV ?
