Indicator multi switch

["A A Ransome" <A.Ransome@onyx.octacon.co.uk>]

Anyone know if the indicator, main beam flasher and horn multi switch 
for a 1973 Midget is interchangeable with another unit (eg. from a 
mini) as mine is broke (main beam and flasher won't work) - thats 
what my local garage told me anyway. A new unit would cost me @ stlg35 
so a replacement interchangeable unit would be a good bet.
Thanks
