Hi Jim, and welcome here at CO2AIR.de. I know this very specimen you have got from the Beeman collection; I've been a friend of the Beemans, several times visiting them and I also had the pleasure to organize for him some sales of vintage airguns from Germany, The Netherlands and Europe for Robert's collection. Indeed he had several ÜbKM1, but he always had only a few filling kits, some even not original. So maybe one of those kits went together with the one of the other Tyrols. The sale of his collection was in hurry (Beeman was very ill at that time already), and sadly there are not many traces left where most samples went.
It's hard to find some info here due to some changes in the discussion board software, but we had a longer review of the Tyrol many years ago (2007):

An dieser Stelle möchte ich euch mal eine besondere Waffe vorstellen die man nicht so oft zu sehen bekommt. Ich selber musste auch einige Zeit suchen um dieses Stück zu erwerben.
Es handelt sich um den 4,5mm Übungskarabiner KM1 des österreichischen Bundesheeres.

You should be able to translate it with Deepl.com, at least to be roughly understandable.
The CO2 versions were quiite popular in The Netherlands, because they have lots of 30M1 shooters and also an own shooting federation, and many of the members owned also the CO2 versions. You can easily distinguish them from those imported to Germany: Unfortunately the imported german ones had a filled-up, closed stock and also cut-off front-side guards.
Most of the Tyrol owners I know have DIY filling kits for CO2, which works fine but isn't of course original.
I will check with some US collectors I know if they could help you out with more info. Takes some days, I guess.
