i have not had time to search further for other sources of information it seemed more important to get something in place with main features given that many statements are presente chronologically in the main source and expressed airly straighforwardly so that using the only information i had at all inevitably makes it similar i felt the revision and selection i made was nore that just slight but as i had no other information i had to leave it as it was i have had no time since then to look further i did put a comment at the end of the source page that i would add more which measn from elsewhere when i had time i haven't found any other source on the founders or the company but given the great omar i felt the founders' names and it should at least have a stub i asked someone at sherperds about the typo in sherpherds site the lady thanked me so i then asked whether they'd permit re copyright use in wikipedia of a photo from their s s archive pref one not already on their website looking out for any reply i dare say she'd have to ask someone more senior before getting a reply and it is august so probably everyone senior is away on hols
