1x winkey is part of a "winkeyless" or original Cherry style keyset, which only contains 84 keys (bottom row only has ctrls, alts, and a spacebar).
The "standard" 87-key winkey layout is the one you would see on a Filco, a CM Quickfire Rapid, or a Ducky, where it adds the windows keys and the menu key.
Most aftermarket keysets (NOT THE BSP ONE, they are an exception) are made to fit a standard Filco/QFR/Ducky out of the box. The charred orange will have the keys to fill out any of those keyboards, as will the IMSTO and Leopold sets I mentioned.
I will echo the statements about Originative and recommend you look elsewhere for your keys. They offer some neat products but the service is definitely less than satisfactory. I'm personally going to be picking up a set of the Leopold keys from ebay now that I have a naked Filco sitting around. You should be able to find used sets of IMSTO PBT or GMK on the classifieds here, but be prepared to lurk hard as they are very nice and thus very popular
N.B. Some Leopold keyboards have funky spacebar sizing. MOST keysets have a spacebar with universal mounts to accommodate, but some do not.
