Does anyone know? | Golf Monthly

Sorry you're quite right. Factory was demolished, don't know what happened to "Mr Penfold" who continued to decorate the entrance for a number of years after GBD ceased to occupy the premises.

If I remember correctly the firm's "Iron Byron", used for testing, stands as a monument by the first tee at Ladbrook Park GC.

Re: any connection between Precision and GBD (Penfold) the fact that they were both Birmingham based was, I am pretty sure, purely coincidental. (Birmingham is a bloody big place)
