Focus wheel cover (3 Viewers)

[dwatsonbirder]

Before I pay £13 (£9 for the item and £4 for postage!) for the rubber focus wheel cover for a pair of the Mk 1 Aurora binoculars, does anyone know of a cheaper alternative?

I'd rather have a an actual cover than use something like inner tube so will probably order directly from Opticron, but a bit reluctant to pay quite so much for what is effectively a small piece of rubber.

Thanks in advance

Any takers?
