New Psvane WE845, Western Electronics 284A Replica

Anyone have more details on these Psvane WE845? Look like beautiful tubes.
Per email, these new Psvane WE845 tubes are same spec as RCA 845 tubes. They look beautifully constructed in the photos. There are many more photos on the Psvane website here:

All the Western Electric replica tubes look to have high build quality. The 1:1 copy of the WE 300b looks great and I wonder if they truly replicate the sound of the vintage WE 300b. Has anyone used any of the Psvane WE tubes? Thanks.
