I need plating and passivating

[meccano]

Well, not me exactly....
To complete a motorcycle restoration to a factory/concours standard I need just 4 x 25mm washers finishing in olive drab passivate.
Anyone know of a local firm that can do this?

This lot in Rugeley may be able to assist - http://www.helpsengineering.co.uk/ .

Mad Mick and Sabatta would have done it - no trouble - but the facilities - and Mad Mick - are no longer available...
