Hanger arrived safe and sound 11.30ish today. Very pleased, it's as expected. Your excellent pics make all the difference in terms of confident buying over the net. As a matter of interest, the frog, which as you said is very a/f, is, as you thought, 'spot on'. On closer inspection it is a mk.1 Naval Frog, designated 'for cutlasses'. Date seems around 1860ish give or take.
By the way, I think your site is very user friendly. Seems to work much better than many and up to date, a rarity!!!
