|@ DigiChromEd: Yes! That is the SFX filter! It's darker than mentioned #29 filters, but it's specifically designed for the use of SFX films. Actually, i do not know what the IR cut-off of these filters is, but seeing it in your picture it does seem to get very close to a true IR filter.
This one's made by Cokin, and in P-series, for which i have no adapters, i do have the normal Cokin set though. PM sent!
@ DConvert: you're right, that could easily be possible! I can't find the specs on the original Ilford filter, but the film has an extended sensitivity to 720nm so any filter would have been within that range. I did shoot a partial roll with a #25 red, although it looks nice it's not giving that real IR "wood" effect. I didn't want to use a true IR filter (i have 750 and 850) because SFX isn't a true IR film but i was looking for a steeper effect than the #25 gave me. Using something in the 650nm range could be the solution!
Thanks for thinking with me here!
Here's a sample from last year with the #25 (Cokin 003) filter:
