HW50 the original version. Spring option

[tinbum]

I don’t think the 99 spring fits. I sold an old 50 to someone and said this they bought a 99 spring and it doesn’t fit. Just saying.

Maccari or the appropriate cut down Titan.

You may be right. I made a kit for a Swedish customer, but having gone back through the details , it was an HW55, not a 50!
