No.
The stripey pattern looks a little like the stripey pattern used on the Onion vases, it's shaped as an uncut Mdina cut-ice Lollipop, so they're still using MH designs and variations on them.
Uncut "Cut-ice Lollipops" are not unusual.

Although you posted an image of a bud vase by Jim Munnelly, made after he left Mdina.
I did wonder if that shape might have been his (Jim's) own design, rather than one of MH's?
It's the round-bottomed, long-necked shape with flared rim, used a great deal over a long period of time at Mdina.
