Keith et al — Yes, your Bohemian looking piece is missing its metal fitting. See Hajdamach II plate 246, row 3(ii), which shows a similarly fitted piece in Primrose (pattern A3226).
What is interesting about these two is that they must have been blown into a multipart opening final shape mould to get the accuracy necessary for the Walsh-supplied metal fittings to be a tight fit. My example of A3226 is like yours, missing its fitting. What is noteworthy about mine is the poor state of the mould lines, by far the worst condition multipart opening mould I've ever seen used on a Walsh piece.
I suspect that mine was made in a worn secondhand mould, probably acquired by Walsh from the Continent, but until I find a match by the earlier glassworks I can't be certain.
What mould lines, if any, are on yours, and what condition are they in?
