Sorry I might have misunderstood, did you mean the case for $1000 or the entire project? If only the case yes for $1000 then yes a ETA movement does not fit right in the J&W case though due to the stem alighnment so that rules out the route.
BTW, I've read that some 5517 deliveries to the MOD had 5513 engravings on them so it's not necessarily incorrect. I can't speak for Eurotimez right now, but I think Narika sells MBW's too.
I'll PM you later about the sword hands.
