Its only an "unholy mess" if people continue to think MkIII parts/MkIII* parts, there is no such rifle as a MkIII* with MkIII parts or a MkIII with MkIII* parts, as i pointed out the LoC clearly states "MAY EMBODY" it is either a MkIII or a MkIII* dependent on the presence of a cutoff, so there is in fact only the one MkIII part & thats a cutoff, all other parts are for & can be used for either.
Forends, now before someones says "there is another MkIII part", yes we see low wall & high wall forends with the low wall giving clearance for the cutoff but these are not model specific parts, there were Armorer instructions for fitting a high wall forend to a MkIII with cutoff & it was not...find the correct pattern or remove the cutoff, it was modify the forend, plus it should be pointed out Lithgow used the low wall forend though its entire production on both MkIIIs & MkIII* right up to the end so if you have a Lithgow with a high wall, the wood has been replaced with a non Lithgow forend.
1915 MkIII*s yep some MkIII*s were produced before the LoC of 1916 & those who produced them were warned their rifles could be rejected if they continued to do so, now the question is..what parts were used? now i have seen & held in my hands a 1915 BSA MkIII* with no cutoff or slot with a forend complete with Volley sights that was numbered to the rifle, it would seem these rifles most likely differed to the early MkIIIs in only missing the cutoff & slot & may be the reason behind the actual wording of the LoC in a bid to tidy things up but don't hold me to that, its just my take on things, it could have been worded that way just so parts already in the system to be used up, or both.
Ironically, the original specs for the MkIII* did not include the absence of the cutoff, just the changes that were listed in part 1 of the LoC so what we consider a post WW1 MkIII was in fact going to be the MkIII* pattern.
ETA the MkIII was manufactured up to & including 1941 mainly by Lithgow but recently a MkIII no star with slot (cutoff missing) Dispersal rifle has turned up.
Will see if i can find the thread, it was on Gunboards.
Here it is, a 1940 not 1941 though
