A little while ago I took a gamble and bought two 400 foot rolls of Ilford Type 617 B&W movie film, on ebay. It was said to have been in cold storage, and had no expiry date, so it was an unknown quantity. Tom A told me he thinks it ceased production in the late 1990s.
The film is rated at 400 iso, so should be fairly similar to HP5. I've shot a test roll today at 400 iso, and developed in ID-11 1+1 for 12 minutes @ 22 degrees C. I'm pretty happy with the results!
I can't quite match Tom A's stock, but this should keep me going for a while!

Lucky find !!
I am reminded of my use of FP4 cine film, about 25 years ago. It wasn't quite the same emulsion as the usual stuff and the best rating was actually a stop lower (64asa instead of the 125asa that I expected) but this could be partially due to the reels being pretty old by the time I bought them (penniless student syndrome).
Of course, it is hard to be definitive on web-pics, but I see that the shadow areas are not so full as might be expected with the dev used. Are the brightest highlights completely black on the film ? Maybe try the obvious bracketing of a repeatable scene, with a range of shadows and bright areas included ? Ilford gives 13 minutes for HP5+ (giving a little under 12 minutes with the higher temp you used), maybe HP5 used a longer time, I don't have any old data handy to check. Possibly gentler agitation, or a couple of degrees cooler would influence the result too - this is all only if the webpics show the same as the negs.
Very interesting to experiment, adjust, and use
