These drawings were mislabelled by William Adam (junior) as being for the Earl of Bath, and on Adam volumes 41/10 and 41/11 this has been corrected to Bute in pencil by Arthur Bolton.

Although also unexecuted, Adam's design for Eyton is quite similar to that by the unknown architect in Adam volumes 39/41-39/46. Doubtless Adam had been given Adam volumes 39/41-39/46 and asked to produce designs along the same lines, as presumably the original, unknown, architect died or fell out of favour with Lord Bute.
