I am not privvey to phillpots set up, but i think the turn around times are way too long.
Last set of stanchions I took to Phillpots, they quoted 8 weeks and delivered in 4. The second set they'd done for me.
Mightily impressed both times and for me, the value of having my original stanchions in new condition far outweighed replacement stanchions at a commensurate price.
Bear in mind they don't just hard chrome fork stanchions for classic motorcycle restorers, they do chroming for many applications across industry, so that will have an effect on lead times.
If you are smart and can plan ahead, then what's 4-8 weeks for a set of stanchions, collected and delivered, in the context of a restoration which is months if not years in length. Just get them off early in the process.
