The Biggleswade Chronicle via GenesReunited has many mentions of High St Henlow in the 30s including house names and numbers; births and deaths; and building plans - you can search and view previews but full articles are by subscription.
If you "drive" up and down High St in Google Street View, there are not many places that fit the description of 1930s brick bungalow (assuming this means detached/single story??) . I'm going to put my money on the one opposite Old Barn Close which I think is No. 88
