Norton Mounting, Head, Filter
Oil filter mounting head for cartridge-filter oil systems, PN 06-3139.
This is the oil filter mounting head listed in the Oil Tank and Fittings section for cartridge filter setups. It's the fitting that the spin-on style oil filter threads onto, tying into the oil lines and tank plumbing rather than sitting inside the engine cases themselves.

The catalog description names it plainly as a mounting head for the filter, and it shows up once in our records for the 1975 model year. Norton is the manufacturer tag here, and nothing in the description points to Triumph or BSA despite what you might see cross-referenced elsewhere.
If you're trying to match this up to your bike, don't lean on the part number format alone — bring in your parts book or give us a call and we'll confirm the fitting matches your oil filter and lines before you order.
