I traded for a dreamy Warwick thumb on here and completely the trade at Waterloo train station. Unfortunately there was no way of really knowing the truss rod was shot at that point.
seller denied the truss rod had gone, so I had to lump out for the bass gallery to fix it.
A lesson learned but I still had a rare (not so compared to your buzzard) bass in my hands and it was wonderful when fixed.
Your bass is special enough to persevere with IMO and if the seller is being a sh*t, don’t put much time into them and leave yourself stressed. Walk away, like our friend who has ordered a Letts bass should have done.
