Ex-Iracian artillery from a private collector for Ukraine?

Phairatic vehicles of at least 5 units were to be spotted in the German town of Bremerhaven and are to come as if from a private collector from the United Kingdom. Where did this russian production of self-propelled cannons come from? After the end of both wars in the Persian Gulf, many countries and many collectors took over military vehicles from Iraqis, including tanks or artillery. They later became elements of the exhibition of museums or private collections. As you can see, respective of them will now most likely be transferred to Ukraine in the form of donations. Much will now depend on the supply of ammunition in a 122/152 mm caliber without which these vehicles will not be able to execute their function on the battlefield. This situation shows how much more weapons can be in private collections or magazines.
