Why are there 22 bids on this canteen & cover?

I can't figure out what is so special about the canteen or cover in this eBay auction.

vtg 1942 US Army Canteen Steel Bottle w/ Pouch Foley S.M. Co. 1943 Insert WW2 | eBay

Probably not so much that it is special, just that there are several ebay members that don't know how to bid and they are bidding in tiny increments. There are only 5 or so bidders, one is responsible for about half the bids.

Seems a bit high to me but I'm no expert on canteens, just what I see selling from time to time.

Crazy price for that rig. :/

Here are some of my cnateens

And it doesn't have the right lid and no cup.

Now if that were a 1943 USS Co porcelain canteen......

That I'd bid on :)
