The Sierra Leone rocket attack destruction story is disputed.
Interesting, I've not seen that one before.
However, following your post I did a bit of internet digging.
What's NOT disputed is that SL's "SOUND ARCHIVE" was destroyed during the civil war. From there it gets a bit murkier as absolutely no one seems to have concrete evidence of what happened to any film material which SLBC may or may not have had.
However, tv servicing only a % of the country, broadcasts being very infrequent, and the main media in SL at that time being radio, it would seem that SLBC wouldn't have had much film material to store away in the first place. However, if it did store anything, no one seems to know exactly where it was stored.
PV has stated that in the 1990's he "thinks" SL still had eps of Doctor Who, though how he is certain of this without having been there and seeing the films or transmissions himself I'm not sure. But goes on to say that certainly by 2000 they were no longer there. Though again, without going there to have a look I'm not sure how he knows (other than 2nd hand) that they were no longer there.
Jon Preddle seems to think the Sn 1 and 2 Hartnell's were sent to Ethiopia after broadcast in SL, which would just leave Sn 3.
As for the out of contract repeat of The Savages, which is probably the source of SL having episodes or not. Reading the "evidence" around this "repeat" doesn't make for good reading.
(Quoted from Broadwcast) "The SLBS purchased four colour Jon Pertwee serials by September 1979. The same set of four stories aired in Swaziland in 1978, Malta in 1979 and Sri Lanka in 1981 (the latter three again in 1984).
With so many disruptions affecting television broadcasts during the early 1980s, it's not clear when (or if!) the four Pertwee stories actually aired: did they play in one continuous run over 18 weeks, or were they staggered over a longer period of several months or years?
As noted above, there have been reports of a repeat screening of The Savages in the early 1980s. This comes from a third party who related the story of a friend's uncle who saw an episode during a visit to Freetown in 1982 or 1983: it was in black and white and featured "the first one with the white hair" and "cavemen living in a wilderness outside a futuristic city who were captured and put in a machine and tortured."
The plot description and the comment that it was the first one with white hair have led some to wonder whether this was an out of contract repeat of the William Hartnell story, The Savages. But the story description (which was told some 26 years after the event, by someone with only a passing interest in Doctor Who and relayed via a third person, so some distortion of memory is to be expected) could equally apply to The Monster of Peladon, one of the Jon Pertwee stories purchased in late 1979.
(Breaking the description down, the "one with white hair" is Pertwee rather than Hartnell (to many, Pertwee and Baker were the only Doctors, so Pertwee would be considered by those to be "the first"; the "cavemen" are the Peladon miners; the "futuristic city" is the refinery control room; and "put in a machine and tortured" could be scenes of those being zapped by the "ghost of Aggedor", being blasted by the sonic cannon, or assaulted by the mind-scrambling automated defence system outside the refinery, as seen in episode three.)
The 1982/83 airdate makes it far more likely to have been a story purchased in 1979 held over for a few years and seen on a black and white set than an illicit repeat of a story that had previously screened in 1970".
So, reading between the lines, I'd be of the firm opinion that SL actually DID NOT repeat screen Savages, and that there is therefore actually NO concrete evidence whatsoever for SL keeping any prints of DW.
For the majority of the population, television in SL wasn't available, and due to its small medium I don't think the broadcaster over there would have attached any importance to keeping shows after airing, certainly, it was less highly valued than radio programmes.
As Jon Preddle posted in another forum, "due to the changes in ownership of the single tv station there, premise moves, civil war, complete lack of importance of film as a medium, it is highly unlikely that any prints of DW would have survived all of that" even if any had been kept.
And there is no evidence other than "the story of a friend's uncle 26 years after the supposed airing and who wasn't interested in DW anyway" that there was actually anything left in SL to begin with.
There's hope and there's a dead duck, and SL certainly looks a very, very dead duck to me.
