Another mixed twist glass probably engraved by the same hand and perhaps from the same original set was in the Julius and Ann Kaplan Collection, sold by Bonhams on 15 November 2017, lot 64 and another from the Peter Eales Collection on 11 June 2025, lot 43. Further examples with related engraving from the Seton Veitch Collection are discussed together in Delomosne and Son's 2006 catalogue, nos.43a and 43c, where a Low Countries origin is suggested.
