20th Paid Mr Samuel Nightingale Taylor for makeing a Strait Blue Great Coat as by his Receipt ...6s

You can be sure that Thomas was not cheated by Alleyne & Roe as his own trade was Mercer.

Alleyne & Roe were a high class establishment as the only other reference I can find is that they supplied Lord Middleton with everything a mercer might supply for a funeral (pall, shroud, gloves etc) in 1774 (the document is held by Nottingham University archive.

I wonder whether Baskett Buttons is another name for Dorset Wheel buttons?

Here is a great coat of the right sort of date. Thomas is unlikely to have been described as a Macaroni as he is distinctly middle-aged by now and lives in the provinces.

Lambskin must be the body of the coat, Shalloon is a fine worsted used as lining. 

In this case "Receipt" means "Design".
