Does your RA117 look like the photograph on the left? By that I mean, is it missing the small brushed aluminium ferrule in the hole through which the 2nd VFO selector switch is accessed?

If the answer is yes, and you would really like it to resemble the photograph on the left, here, then I can supply you with a replica ferrule.

These ferrules appear to also be a feature on the RA1217, where there are two.
