Help ID Satsuma mandarin variety

[sc4001992]

Just wondering if anyone else had a cluster of fruits on one branch that has so many fruits ( total of 24).
This is a Satsuma scion branch that is about 2 years old on a grapefruit tree.

The fruits on this branch is smaller than normal but the taste is still good. I got the scion from UCR budwood but lost the tag. Can anyone help identify this Satsuma ?

I had a similar issue with oroblanco branch that had 110 fruits (normal size) on one large branch, it ended up braking off just as the fruits were yellow and almost ripe.

Kishu Mandrin??? Got seed? Color inside?)

I have a few kishu trees with fruit now, they are smaller fruits.
These are maybe 1.5x the size (ranges from 1-1/2" to 2" diameter). Still taste good but not as sweet as kishu.
I will take a photo of the kishu fruit next to this one for comparison. This fruit may normally be slightly larger but due to the big cluster it might have smaller t than normal fruit. This is the first year the branch had any fruits so I didn't notice it until I looked up into the tree.
Somehow I had mislabeled this one as Kiyomi Tangor which is a big fruit, size of an orange.
