Continuity mistake: At the retirement party when the carriage clock is first seen on the table it is showing the time as 10.10 but when it is being presented to the officer the time on the clock is now 10.05.
Other mistake: Early on in this episode Regan is moaning about lawyers earning £30,000 a year and that he himself can just about afford a secondhand car, but later on in this episode he is driving a M registration ford Capri, which would have been brand new when this episode was made.
Suggested correction: He is being metaphorical. Reagan is known for his florid turn of phrase.
