King’s College London AKC gown

Hello,
Some years ago I designed the epitoge, with gold Reggie the lion motif, so that AKC’s could be recognised when wearing the new KCL academic dress, and I worked with Dame Vivienne Westwood in her new designs for KCL robes (sourcing fabrics and choosing colours).
Currently, I’m writing a paper on the introduction of academic dress for Associates of KCL, for Transactions of the Burgon Society www.burgon.org.uk and have the story of the three AKC hoods and also the various gowns worn by students of the various departments, but there is nothing in the Council minutes or Secretary’s letters about the AKC gown with velvet facings. I’ve also searched back through all of the College calendars and anything else that looked likely in the KCL archives.
Some time ago I saw a post from someone which mentioned the gown. I know what it looks like (and own one myself) but the silence about its introduction, in the official documents, is strange.
There are references to it in robemakers’ catalogues. The earliest reference I can find to it is in ‘Notes & Queries’ 1864:
“Superfluous information would only encumber your valuable pages, but accuracy even in little things is most important. Associates of King’s College, London, wear no hood, but simply a gown with velvet border. The black and mauve hood is worn only by Associates in Divinity.”
The calendars from 1860 say that AKC’s had the privilege of dining at high table, in college, if wearing academical dress (but doesn’t exactly mention the AKC gown).
The first AKC was awarded in 1835.
The gown was worn by all types of AKC, whereas the hood was granted to AKCs in the Theological Dept ‘in holy orders’.
Any illumination of this mystery would be gratefully received and acknowledged.

I seem to think that somewhere in the Burgon Society publications there is a note on an Aberdeen shape AKC hood which was not connected with the later AKC (Theol) and which, if I recall, was blue edged red.
