...looks to be one lacking decimal points. While the main description and picture show it as RED, other parts of the listing describe it as GREEN.
Might be worth dropping a query to the seller to ask which colour it really is / whether he also has them in green. No indication of size either, which is not helpful.
If it's red I would go with the one kindly offered by Restoration73, assuming his is either in or from a Cybernet set.
