This one seems to have a number of names. It started off as the Eurocco and then became the SN1. Manufacturers have included Embeesea (Eurocco), Steaney Developments (SN1) and Amplas (SN1) then in revised form by Lemazone. I've got the same picture captioned as a Steaney Developments SN1 but it could be listed as any of the above.
