Attn Philadelphia PA Area Spitfire Owners: Shop Question

[Matthew Milkevitch <mmilkevitch@yahoo.com>]

Fellow Philadelphia PA Area Listers;
 
Does anyone know if PowerBritish (located in Plymouth Meeting PA) is still in 
business?  I've attempted to phone them and I an unable to get in touch.  
Perhaps their phone number has changed?  Any information would be helpful.
 
Thanks,
Matt Milkevitch
