In Fawlty Towers, what regiment's tie does Major Gowen usually wear?

In Fawlty Towers, Major Gowen usually wears a Royal Artillery regimental tie.

Major Gowen is the hotel’s elderly, slightly senile permanent resident, played by Ballard Berkeley. His jagged-striped Royal Artillery tie is a visual reminder of his military background and helps establish him as one of the hotel’s old-guard characters. He is generally amiable and one of the few guests Basil treats with genuine respect.

The Major frequently talks about events beyond the hotel, especially cricket scores, labour disputes and his memories of wartime Britain. His military identity also informs his old-fashioned attitudes, which become particularly uncomfortable in “The Germans”, where he discusses the Second World War and expresses racist views.

The tie is easy to confuse with insignia associated with other British armed services, such as the Royal Marines, Royal Signals or Royal Engineers. However, the series’ character description specifically identifies Major Gowen’s usual neckwear as Royal Artillery. In “Waldorf Salad”, Basil says the Major has lived at the hotel for seven years, reinforcing his status as a long-term resident rather than a passing guest.
