I intend to now.
Funny it wasn’t until I saw the photo that I saw the grub screw clearly. I’d better get to SpecSavers!
I have the EM Romford/Markits axles on hand so I will be trying it this weekend. If successful i will order the bogie and tender wheels. I have two other OO Works locos that will hopefully be the same. Also there are a few for sale on eBay at the moment. It could be a very cost effective way to easily convert a few locos.
