Boulanger's Knitwear, Motspur Park

Does anyone recall the knitwear factory of Boulanger adjacent to Motspur Park Station? My mother worked there from the early 1950s through to the mid 1970s - a long while! Perhaps there are people - if I recall, mainly women - who worked there and perhaps who remember my mother - I have vague memories that it was a low prefabricated looking building - they made fashion tops - all very 1950s! and probably highly collectable now.
