I have to admit when I first saw them on the sprues I was a bit dubious about how well these two sets would fit together and whether they would look any good.
Having spent a bit of time assembling them this afternoon I have to say I am impressed with how they look.
Note - I have not pictured the orcs that came with the catapult as I won't be using them myself. I have also added some brass rod handles. For the pictures the catapult is held in place on the trolls by Blue Tac. Super glue also seems to have held the catapult parts together ok.
Made from Dark Alliance set 72033 War Trolls for Catapults and Dark Alliance 72034 Orc Catapults. Available for sale here: https://www.drumandflag.co.uk/search?q=trolls
To see painted versions surf Google where other hobbyists have blogged their work.
If using with GW figures these will be on the small side given that they are made to 1:72 scale. The standing Troll is about 60mm tall for example.
