[drakelist] Blue filter gel (C-line)

[David Austin]

Just trying to get hold of some new filter gel for the displays on my C-line. A previous posting suggested that Drake actually used a Rosco filter material known as Roscolene #853. I have been in touch with Rosco (UK) and they say this is a discontinued gel series. Does anyone know of a source of the original Roscolene #853, or if not, the nearest equivalent gel in one of Rosco's (or other manufacturer's) current range? Rosco tell me that there is no direct equivalent, but someone else may know of a satisfactory match?   Thanks and 73   David G4GTP
