  Recent work of Ablett arXiv:2112.03400 and Kapustka, Kapustka, Ranestad,
Schenck, Stillman and Yuan arXiv:2111.05817 outlines a number of constructions
for singular Gorenstein codimension four varieties. Earlier work of Coughlan,
Go{\l}\c{e}biowski, Kapustka and Kapustka arXiv:1609.01195 details a series of
nonsingular Gorenstein codimension four constructions with different Betti
tables. In this paper we exhibit a number of flat deformations between
Gorenstein codimension four varieties in the same Hilbert scheme, realising
many of the singular varieties as specialisations of the earlier nonsingular
varieties.
