The roller was not included with the original sale so it’s been sat in my garage for a while. I have since procured a close match made of nylon from speaking with the team at pacer marine and it requires the stainless steel bolt and washers to complete. This was bought as part of a restoration project in an early 1970s Shetland boat but was not fitted. The casting is made in England (see stamp) and has been factory drilled and tapped ready to fit the guide wheel. YS bow rollers are known to be of excellent quality and made of superior materials (look this up yourself), you are buying one of the best!
It was expensive when bought originally as new old stock off eBay and it’s supplied with a new roller. Sizes are on the photos. Some storage marks and scratches as can be expected however, the is very fair to reflect this as it’s less than half price!
