All the gears and the bearings are back on the pinion for the '53's gearbox.
Just checking all the gears select OK and then the two halves can be joined again.
Although it wasn't without drama, the box was on the bench and something fell off the shelf and landed on the reverse selector !
The end snapped off, but luckily well known vintage parts guru Filip Garsbeke is only 10mins away. A phone call was made and soon enough we were back with a NOS reverse shifter.
Thanks again Filip for saving the day ;)
Guess the lesson to be learned here is "less haste more speed"
