These bearings are kit 15023BS. They are original British Timken from 1957 stock.
See the chart below for the overall picture. The line relating to these exactly is in Bold larger font. This kit is for 1951 to 1952 Morris Minor as shown.
I don't know in what way they are different to the kit for 1949... I surmise there is a spacer involved... but...
I don't know how/if these MAY also fit later ones. The catalogue in question MAY be from 1952/3, in which case it cannot possibly know the future. I am not able to say anything on this subject, but I just mention it here, as you may wish to follow it up yourself... with a person who knows what the diff morphed into later... or not...
Ultra rare... you will not see this again anytime soon
IF ANY OF THE FOLLOWING RULES AND CONDITIONS displease you, then the solution is simple... don't buy them. I must be strict due to "certain people".
Sorry, I will not pull the package any further apart than the photos show. I will accept returns to some extent, but if the wax paper packaging is in any way removed, tampered with, further torn than the photos... then $125 will be deducted from your refund, as their pristine untouched condition is what people want. All freight to you will be forfeit. Freight to return is your cost.
LOCAL FREIGHT signature and insurance are compulsory, and are included. Ebay's ripoff freight-fee of $3.50 is also included. I will only use Aust Post for this item, which is expensive.
OVERSEAS This is 1.4kg. Australian freight is very expensive. I have used a flat $95 rate, as signature ($6) and insurance ($12) must be included, which Ebay will not add in. Also Ebay's 15% fee is on freight too (a total ripoff) and that $13 ripoff is also included. Aust Post is so expensive for items over 1 kg as this is, that it MAY be cheaper to use the faster UPS Express etc (especially USA). I will check for you.
