Hi Robert & All,
Thanks for all the fascinating information Robert!
Another couple of galaxies that fit this description are NGC 3628 (the well-known third member of the Leo Triplet with M66 & M65).
Not a particularly strong example, you can make-out a wide "X" superimposed on the centre of NGC 3628 that is a strongly disrupted spiral with a warped disc that clearly shows up with the bifurcated dust lane in the plane of the disc.

For the last day I've been racking my brain to remember the designation of another stronger example that I could recall from seeing a Hubble image but do you think I could remember the catalogue number? Well tonight it came to me -- it is ESO 597-36 which is also Hickson 87A in Capricornus. It too has a bifurcated lane in the plane of the disc.

ESO 597-36 is the brightest in the group (that's why it has the "A" designation) at mag 15.1 -- it is on my hit-list for a fortnight's time! The eg in Hickson 87 lie at about the 390 million ly mark.
Best,
Les D
