Now Patowalker has posted the reference, do you get it?
Patowalker didn't post a reference or citation; he copied a few lines.

Get what, exactly? At what point in the information posted is the aviator directed not to include the airport name during each transmission? Where is the user expressely told not to do so? Where is the user told not to use the aircraft type in each transmission?

Oh dear! Its very British to prefer to obey rules, rather than achieve the spirit of regulations.
Quite, but where the the rule advising against or prohibiting using one's aircraft type along with the callsign, and announcing the airport at the beginning and end of each transmission. Nothing about being British or conforming to LASORS (or CAP413, for that matter) would lead one to do otherwise.

CAP 413, Chapter 2, 1.8.2 (http://www.caa.co.uk/docs/33/cap413.pdf) does say:

"The name of either the aircraft manufacturer, or name of aircraft model, or name ofnthe aircraft category (e.g. helicopter or gyrocopter) may be used as a prefix to the callsign."

http://www.caa.co.uk/docs/1615/safetycom_review.pdf

The Safetycom Review Final makes the following comment regarding use of the aircraft location in each transmission:

"Because SAFETYCOM operates on a single frequency throughout the UK it is vital that pilots include the location at which they are operating, otherwise the information they transmit is useless to other pilots. All transmissions on SAFETYCOM should start with the phrase ‘XXXXX Traffic’, as explained in Chapter 4 of CAP 413 (Radiotelephony Manual) and Safety Sense Leaflet 22, which is published in LASORS."

Is it really such a stretch to see that the transmission is wisely ended with the airport identification, as well?

The Safetycom Review Final goes on to state:

"The importance of including the location in transmissions made on SAFETYCOM will be strongly emphasised in future information regarding the frequency."

Regarding using the radio to look for traffic, as some are wont to do, the same Review Final states:

"Pilots should also be aware that non-radio equipped aircraft operate widely in the UK’s uncontrolled airspace, and SAFETYCOM is not a substitute for good lookout, but an addition to it, to be used only within 10nm of the aerodrome and below a height of 2000ft above the aerodrome elevation. It is for the pilot to decide on the most appropriate frequency in the circumstances of the flight. Pilots should also be aware that not all other aircraft will be operating on the same frequency. As ever, good lookout is essential and SAFETYCOM is only an addition to this."

CAP 413, Chapter 4, 6.1.4 states:

"All transmissions at unattended aerodromes shall be addressed to '(Aerodromename) Traffic'. No reply to an unattended aerodrome report shall be transmitted."

Note this is all transmissions; all transmissions will include the airport name.

Perhaps most importantly, 6.1.6 states:

"Unattended aerodrome reports are made at the discretion of the pilot. However, to ensure the traffic awareness of other pilots is correctly maintained, if a pilot elects to make reports, all those reports not listed as ‘optional’ should be included. Optional calls (illustrated in paragraph 6.3) may be included if additional traffic information is likely to assist traffic organisation or to enhance safety."

While British compunction may insist on adherence to regulation and rules, CAP 413 specifically states that calls are at the discretion of the pilot.

Unless frequency congestion dictates otherwise, there's no good reason why one shouldn't use the aircraft type or identification in the callsign, and end it with the airport location.

Yes, I do get it.
