Parliamentary Writs

It is stated in Duncumb's *History of Herefordshire*, 1. 154. that "the writs, indentures, and returns, from 17 Edw. IV. to 1 Edw. VI., are all lost throughout England, except one imperfect bundle, 33rd Hen. VIII." This book was published in 1803. Have the researches since that time in the Record Offices supplied this hiatus; and if so, in which department of it are these documents to be found?
