Alas I no longer have the magnetic film.

For sale on ebay, with less than a day left. It’s not described as for a Square Four, the seller thinks it’s Triumph/Ariel (!) It’s currently at £6. Ebay item 335874679385 Nothing to do with me etc,

I’m sure your inbox will have a few messages with offers of project bikes, but if not the Draganfly site has some, they would probably ship abroad if you are not in the UK.

I too have sold Ariel bikes on Car and Classic, so agree with Bernie’s comments above. I used the listing option and not the auction. The listing option is free.

It’s worth noting that there can be a difference between paint and powder coat for the same colour. Even black can be different between the two.

There was a post on this forum of someone who did this in their home workshop. It had pictures of the set up. I think it was posted by Paul Wirdnam.

Very nice example of the mark 2. I’m sure you will take your dad as a pillion up and down the drive.

Yes and Yes, on my square fours.
