George Radion in Australia has a database on Australian-made Jacks

This database is for vintage and classic Donald W Sessions (DWS) vehicle jacks.   Many of the photos and comments have been gleaned from Ebay and other sites.  I would be pleased to add photos and comments from anyone who has information on these jacks.

Please note that this information is accurate to the best of my knowledge, but I make no claims about authority on this subject. Use your own discretion when evaluating the accuracy of the information.

The values are normally taken from auction sites world-wide, but exclude postage.

Request to vendors: Please feel free to use the information from these databases in your adverts. An acknowledgement of the source would be most welcome. However, please do not twist any of the information. Where I say along the lines: 'May be for car X' please make this clear in your advert. An altered statement saying: 'It is for car X' will create false facts and misinformation. If you know for certainty a jack's heritage please contact me so that I can amend the entry. Thank you.

This jack or similar Smiths versions were standard fitment to a 1937 Riley Falcon sedan, complete with bracket (2nd to last photo) to attach to the bulkhead.  It was also likely fitted to the 1936 Riley Merlin and may possibly have been used in 1938 on the Riley Victor. The photos shown have the Riley tapered fork which fits into a bracket mounted on the chassis on each side under the centre of the running board .

This jack was also supplied with various shaped lugs to suit other cars.  The third from last photo shows the jack stowed on a 1937 Riley Falcon. The final photo is from a 1937 Riley Falcon 12/4 handbook, courtesy of John Spratt.
