The Stewarts & Lloyds Limited's 6-wheeled No.25 built by the Yorkshire Engine Company in 82 is the ultimate 6-wheeled ogee built for British networks far as I'm aware,

though some others were exported after this date.

Nice to know about Andrew Barclay's clean switch in tank styles
Have never researched them or Barclays & Co in great detail but they certainly did build some smart boxes, the former's Works No.133 sold to The Dalmellington Iron Company was a right monster though! While capacity and adhesion would take a hit can't argue ogees do have the edge for visibility when shunting so that might be the reason, though when it comes to Neilson there isn't always much rhyme.
Below is their earliest ogee I'm aware of.
The angle isn't the kindest but it appears the cylinder pipes are not exposed so this stepping stone design is presumably from 1860 or a little after. That said the crank pin holes are between the spokes which doesn't gel with the later pattern that Bob Ridley/Phoenix and the eBay photo example sported so a little hard to judge on just this early 67 photo.
Pinkie is the next earliest 4-wheeled example I'm aware of and the more standardised piano & round saddle design that Neilson churned out can very much be seen, the 1888 engine in your post above being something of a throwback in terms of its exposed frames.
A few other Scottish firms built boxes and pianos for a time too, no doubt a fair bit of transferring talent and direct copycatting played their part.

1078 1865 ?-?-?T Outside? 4' 8.5" 10" cylinder tank owned new by A. Wilson who constructed the Esk Valley Railway. Authorised 21/07/64, first sod cut 05/09/64, Esk Valley Junction-Polton opened 15/04/67. Later owned by Wm. Black & Sons of Stanrigg Colliery, Airdire 05/72
1082 1865 ?-?-?T Outside? 4' 8.5" 12" cylinder tank owned new by Waring Bros & Eckersley who constructed Solway Junction Railway. First sod cut 28/03/65, opened to freight 13/09/69 & to passengers 08/08/70 (some sections earlier).
*There is an outside chance this was an 0-4-0ST ogee No.'6' or '8' was snapped in Jan 67 near Richmond Terrace. This concerned the Metropolitan District Railway contracts which Waring Bros was also involved in. Then again it might simply be another Neilson.
