Factory Service Unless it has been severely damaged we can restore virtually any B&M siren, of any vintage, to its original factory performance.   Each siren is serviced to the customer's specification, from basic mechanical repair to complete restoration, refinish or upgrade. Service and restoration work is completed to the finest standard, using only Genuine B&M parts.   Genuine Factory Parts Please be aware that some components may resemble common 'starter motor' parts.  However, due to the unusual requirements of Siren Service, the use of non-factory parts may reduce performance or cause damage to your siren.  B&M Genuine Factory Parts have been engineered to give the best combination of performance and longevity.  Contact us for Factory Service and Parts information.
