Oil tank for Bachmann 4-4-0 tender

[NevinW]

I've been looking for the oil tank that fits in the Bachmann Spectrum 4-4-0 tender.  It comes with the accessories for the undecorated version.  I found the complete tender shell for sale in the parts section of this web site but it doesn't indicate if the oil tank comes with it.  If the oil tank is sold separately, I can't find it in the parts section.  Any thoughts or suggestions?  I like this oil tank better than my current ones.  -  Nevin
