HGSS – admin@HGSS-global.co.uk is still listed on Holt's web page. HGSS ltd was a different company. Perhaps a email to them, Holt's, will help. Holt's has responded to several questions about shippers and collection of my lots or sending them with an importers lot for shipment to the US. Just ask them for current contact information and any phone numbers they have It might be different that those posted. I do know there was a retirement "recently" so that might be the bottle neck.
