The double method search completed in 3.5 hours, but yielded more results
than I was expecting i.e. 10 million. Not much chance of the non double
search completing then! It could take a while to check whether there are any
good ones among the 10m, so I ran it again eliminating pn56 (and the
corresponding pn12) other than at the half lead. This gives just sixteen
results. Of these, No 5. is probably the most distinctive, although No.1's
treble path, while not meeting Mark's right-place criterion*, does have good
progression from front to back (first quarter lead on the front four and
second quarter lead on the back four).

Regular Double Treble Place Minor methods with a Plain Course Extent (no
single change notations, and no pn56 other than the half lead)
