As you can see from the photos, the red hoses are badged Samco. Whereas the blue hoses are unbadged. They appear to all be made from the same materials

Hopefully if you are reading this you know what you are looking at. From what I can conclude the blue set are for a 999/749/s, and the red set are for a 916/748. I've compared both sets to new hose sets for sale on ebay and both sets are incomplete.

There's no apparent holes or splits. These were amongst a box of parts I bought last year.

Happy to answer any questions or send more photos
