Seven rim Vase. Qianlong mark?

Hi, I picked up this vase at Goodwill. It was filthy and had hard water deposits inside but I thought it looked unusual and I couldn't resist buying it. It feels thick and heavy. Looking down the smaller rims, you can see the cross section where the vase was cut open and connected to them before glazing. I tried to find the mark in some online libraries and from what I can tell, it seems to have several characteristics in common with marks that were identified as saying (or being) "Da Qing Qianlong Nian Zhi". I could be way off. I was hoping you could tell me more about it.
