I'm indebted to David Howe for freely supplying more information on Ulster reference numbers and corrections where necessary. Thank you.
1. Parts common to production supercharged and non-supercharged Ulsters are 9C. eg: steering box and rear shock absorber links.
2. Parts only on the non-supercharged production cars are 9E.
3. Parts only on the supercharged production cars are 9C - primarily the engine and ancillaries.
4. 9B numbers are found on Works only parts.
5. SP numbers are found on Super Sports, supercharged engines
6. 1A numbers are found on both 8-stud supercharged and non-supercharged blocks as these are Longbridge modified standard castings.
7. 9C numbers are found on 10 stud blocks, both types.
8. 1 5/16" Ulster cranks will be stamped " Ambrosia " as this company were their manufacturers for the AMCo.
I'm sure the above data will be useful to those wishing to identify or to build up early sporting Sevens.
