1.q Norton 1920's and Earlier 1930's Models - All Parts/All Models

- This is a high quality facsimile of the original Norton 1925 Spare Parts Catalog, but printed in A4 format - to give additional clarity. This has to be rarest of all Norton Spare Parts Lists - and covers all Flat Tank Side Valve models, as well as an additional section covering the very first OHV models - making this an interesting and excellent read, even if you are not lucky enough to own a Flat Tank model!

We print these pre-war catalogs in larger format as they did not use 'Exploded' diagrams - therefore A4 format makes the pictures much easier to see.  All else as per original - see detail information for more information. 

- This is a high quality facsimile of a very rare publication - the Maintenance Instructions for Touring and Speed Models from 1925, and it goes alongside our Spare Parts List from the same year - providing useful information for anyone owning or restoring a Flat Tank Norton. 

We print these pre-war catalogs in larger format making them easier to read  than the original A5 format - therefore A4 format makes this catalog ures much easier to see.  All else as per original - see detail information for more information.

This is the single row roller bearing as fitted to both sides of the SOHC Walter Moore CS1 and CSJ 1927 - 1930 engines.  It was also fitted to Model 18 engines of the same period. These are the correct original 'C3' looser fit bearings - from the NKE brand (These are an Austrian/offshore named brand of reasonable quality - but not the original RHP UK Brand which are now unavailable).  See listing for more detail
