thank you, yes you are right, it is a type D.
After some investigation the way to tell type Ds from type Es (if you don't have measurements) is the type D has "Post Office" on one line under the cypher and type E has "Post" and "Office" on two lines under the cypher.
I have updated the osm wiki to make this clearer

Geek Retreat closed down many weeks before your edit

The substation name will be on a sign on the door/gate (from memory) giving the substation name, the name of the electricity board and a phone number to call in case of emergency.
I don't think the Haxby one will be called Calf Close as it is not actually on Calf Close (maybe it was named after the Calf that Calf Close was named after? was there a Calf pub before the houses were built)
There are quite a few oddly named, often referring to what was next to the substation when it was built eg Leak & Thorpe (a department store long gone) or York Viking (after the hotel) or Huntington Brewery

Which bit? The "YOR" seems to be a common abbreviation for York by the Electricity Board at some point - there are ~ 16 other substations in York with the (YOR) suffix

Fair enough, if it is not there any more. I wonder if it has been moved somewhere else - maybe nearer the centre of the village.

just a typo, thanks for spotting this, now fixed

oops! I must have been relying on autofill too much - now fixed

oops! yes, thanks for spotting this

Maybe someone mistook one of the safety lights on the fire escape for a defibrillator box?

oh I didn't spot that on the map, no the defibrillator is by the cafe entrance not by the fire escape
I will fix it

oops, thank you for spotting this, it was just the enterprise hire car and the motorbike shop that are going to be become student accommodation - have fixed this now

I would call it a wall box as it is clearly mounted flush into the wall - I don't know why the LBSG call it a lamp box, maybe they have inside knowledge why Royal Mail would mount 1000s of boxes designed to be mounted onto a pole into walls.
Whether it is pillar next to a wall or a wall extension doesn't really matter.
But for the average map user, knowing they would be looking for a post box built into the wall is the important information.

has it been moved indoors now?

Hi, are the phone boxes back? I thought they had been removed a few years ago

hi Dan,
thanks for noticing this, yes, you are right, I have corrected it

which ones are you referring to? i removed the ones for Kent Street as they were for a kent street not in york

Thanks, wasn't sure it was right, but the ID editor was very keen to suggest it

Hi, Grade II is more normally written using roman rather than arabic numbers
