Restoration specialties in PA, should have all those. If you can send a sample to match even better. DL
If you need the screws and don't require exact originals you can get #8-32 x 1/4" philips truss stainless steel head screws/bolts and polish them to look like chrome (the originals were chrome plated). If you can't find any then I have some of these in stainless.
