The name is so well known but it's unusual to see it actually on a guitar - and an acoustic guitar at that! This particular Marshall Bluesbreaker acoustic guitar is currently being offered for sale on eBay, although unfortunately has sustained some damage to its rear. These were distributed by Rose Morris (I'd guess in the 1970s) and were - the seller claims - actually made in Italy by Eko. The eagle-eyed will notice that this Marshall Bluesbreaker is nearly identical to the Eko Ranger other than having a different shaped headstock and - of course - the Marshall name applied to it.
However, I'm wondering if perhaps they were made by Fratelli Fuselli (Fuselli Brothers) who produced the E-ROS Dakota fashioned after the Eko Ranger design? I'd say there was more of a resemblance.
