Hi guys

I was wondering if someone was able to help I'm looking for a 1/35 scale model of the WW1 German 21 cm Mörser 10. It can be resin or plastic (would prefer plastic). I have a commission to build one but I'm having trouble locating one. I've found a Verlinden kit of the gun as it was used by Nazi Germany during WW2. Does anyone know of or have links to where I might get one??

Cheers in advance for your help
