Sadly that's not quite the right one! I ordered a Pilo D175 previously (
https://www.ebay.co.uk/itm/126973085889) but, while the hanger is the correct shape, the holes are drilled differently. Apparently D175 is Principia part number PA082007, whilst I need PA082000 - which they don't make. The only difference between the two is the distance between the two holes as you can see below!

Anyway, apologies for hijacking your thread, I am just desperate to keep this lovely frame going - it really is fantastic and I wish you well in selling yours!
