White hoods for shimano BL-1051 brake levers

[foz]

I know these might be difficult if not impossible to find, but I would like to get hold of some white hoods for shimano BL-1051 brake levers (the first 105 levers with aero cable routing, I think)

I have some grubby white ones, but am after some NOS or pristine ones to replace them

Thanks!
