I think crosman licenses the Remington name in the US. Maybe someone else licenses in the UK? Even the break-barrels don't look like crosman product.
The UK is excluded from the Remington licensing. https://www.crosman.com/connect/crosman-acquires-exclusive-license-for-remington-branded-airguns/
Remington branded products are imported into the UK by Sportsmarketing (SMK). This company has done this for a few years now. At one point the owner sold the company to Remington and although it remained with the same trading name. The holding company was known over here as Remington Outdoors. However, when Remington needed to divest some of its business, the original owner of SMK who still ran the company for Remington, bought his company back again.Solware is only a retailer.
