Evening,
Paralell to building the Model A, i started collecting tools for the toolkit. Finding a prewar G1/59 5/6x3/8WW O/E Spanner though is proving elusive.
Plenty of postwar G1/59 are about though.
Can anyone help?

Nearly there but this is when the “fiddling about” really starts to rack up time!

Evening….just a query to those 27-29 owners about the engine’s exhaust valve lift mechanism. I’m currently trial-assembling this mechanism into the timing case on my 28 SV and whilst I can get it all installed etc, there is only a tiny amount of lift. Notably though there isnt any contact wear on th...

Finally back to the 28.
Lots of fettling to get the timing bush into order and crank running properly but got there in the end.

Its just the G1-55 spanner in the factory toolkit from 1927. I see them on ebay all the time often cheaply. a few seconds search…. https://www.ebay.com.au/itm/256272150511?mkcid=16&mkevt=1&mkrid=705-154756-20017-0&ssspo=bT-Kl6j4QAK&sssrc=4429486&ssuid=qUiXUuvKT3a&var=&wid...
