It took a few days before the penny dropped for me with this house-name from Imperial Avenue, Gedling:

For the benefit of those whose only connection with English is Received Pronunciation (“RP”):

Those speaking RP will always pronounce the ‘H’ in “his” or “her’s”. There are many regional dialects within England that would never pronounce the ‘H’ (mine own dialect was Yorkshire, although now diluted by spending 30+ years in Nottingham). It is most typical within colloquial English to hear the ‘H’ dropped in such words.

PS
What a classic street-name for the 1920/30s!
