clear, traditional shaped glass moulds without any id are common at boot fairs - antiques markets etc., and usually very uncommon to find one with any provenance - and I do look at most that I see.
I don't know if this Harry Peck example is of any interest David - I have to admit to never bothering to research the piece, but would assume by the evidence of wear that it must have some reasonable age.
The wording, in upper case, is in relief on the ledge below the six domes/bobbles, and says.....HARRY PECK & CO., and SNOW HILL LONDON.
The mould is about 5.5" (140 m/m long), and the domes have deliberately flattened feet which show reasonable wear.
