As posted by both the East Yorkshire Enthusiasts Facebook Page and by Mr Gilbert:

In addition to 791, 781 (YX14 HEU) is also now refurbished and was collected today
782 (YX14 HEV), 790 (BP15 OLC) and 792 (BP15 OLG) are presently away at Bus and Coach World undergoing refurbishment - 792 being the example taken over today in exchange for 781
While both batches are undergoing the same treatment, it has been flagged up that they have different seat types - 790-2 having the same Esteban Civics as fitted to GNE 6118-21, while 780-5 have Rowan Telmac, the same as found in Arriva's 7401-6.
A second 'Beachcomber' B7TL/Gemini is approaching completion at Ensign - this being another one for Scarborough judging by the picture (see the comments in the post linked below)
