Ancient Celtiberian (Celtic) or Roman vessel (lampholder?, inkpot?) , likely from the Iberian Peninsula; from old collection of bronze items

Unique small bronze vessel from a Celtiberian collection of items; I've spent many hours (and reverse image searches) trying to find a matching example and came up lacking (if you know of one, please do alert me). It is a ribbed vessel, with one hole much larger than the other. It seems likely that the bottom hole was plugged and it was used to hold something like ink, or a lamp stick (incense, etc). It's possible that the object was used as a spindle whorl or fishing weight, or something else where a string went through, but it seems unlikely as those objects were not typically this well designed or decorated... and the hole size would be the same on both ends..

The vessel is from a Celtiberian collection of artifacts. It is made of bronze. It measures approximately 24.3 mm high and 25.2 mm across its widest part.

Wikipedia tells us the Celtiberians "were a group of Celts and Celticized peoples inhabiting an area in the central-northeastern Iberian Peninsula during the final centuries of the BC. They were explicitly mentioned as being Celts by several classic authors (e.g. Strabo)."

Provenance -
Someone wrote, what appears to say "Libia" on the side. This likely coincides with the Roman Libia, located near Herramelluri, La Rioja in Spain.

We bought a collection of artifacts at auction in Switzerland (La Galerie Numismatique, September 28th, 2024); we are researching each object and offering them for sale individually. You can see the entire collection in the pictures we posted.

In the course of our investigation, we found that the artifacts had several names of places in the Celtiberian region written on them, for example "Salienca". Also, the collection's brooch design was unique to the Celtiberians (Google search "Celtiberian Fibula" to see similar examples). We've come to the conclusion that the collection is specific to the Celtiberian era/region.

Condition -

The bronze has a patina of green. A 1/4 of one of the top/bottoms is chipped away. To glue the vessel into the collection, it seems like the collector filled it with glue from the top; the center is filled with glue-like material and I don't think it's ancient (could be wrong though, maybe it's the remnants of what was in it). There are some remnants of glue on one edge, where it was glued into the collection. Several marker marks, the bottom's mostly lost, but the side clearly says LIBIA.
