Hope Mini lever seal - FOUND

[development_cycle]

By chance does anyone have a spare seal/diaphragm for the lever/master cylinder of a Hope Mini? I have been trawling the interweb, and not only are these hard to find, especially in stock, but they seem to vary considerably in price, and come most commonly in a kit with other bits I don't need. Where I have managed to find them, by the time I have added the postage cost it's like over a tenner fore one!

This is the Hope part number HBSP112

I have included an image of the part, and if helps the lever too.

Thanks
