So i am new to seraphon and just got into games workshop after 20 years away Anyway i nroke the tail of the rider can i put a alternative model on there rather than buy the whole kit again
You can reglue the tail. But to answer your question yes you can proxy a different model 99% of the community is okay with people using proxies
Also if you're looking for that same tail it's kind of hit or miss but there are usually Seraphon bits for sale on Ebay.
