Hi Pete,
If they were WW2 original cleaning kits with pouches, and accessories, and the chargers and take down tools were all original -
the issue is these do not look, even through the zip-lock bag, like originals - then the price is within the realms of reason.
However - type in Sturgess in the search option at Simpsons, you will see it is being used to sell mediocre items alongside choice items, but, doubling or in the case of the MG15 magazine unloader, four times the price of even IMA -

It was just an observation, I thought I'd see what others thought before sharing my opinion.
I was there for the $750 FG42 sling (also from the "Sturgess" collection - but unmarked and with one disappointing photo - it's not tempting enough for me to fumble for my credit card.
All these high end collections sold, posthumously - seem to be loaded with reproductions and questionable items, I know mine will be, if it's not liquidated before my death, lol.
