Steering wheel restorations turned round a wheel for me in less than two weeks from me sending it, to getting it back. The boss was in good condition, but it had two broken spokes at the boss end, which they repaired very nicely at no extra cost. The overall finish was excellent, and probably better than could be done at home. Whilst it is not cheap, about £350 including two way postage and VAT, you do have a wheel that will last for years.
I collected quite a few wire spoke wheels over the years looking for one to restore; the main problem is not that the coating wears off the rim, but that the rim becomes very thin. On one, the boss'd had 7 bells knocked out of it by a PO, presumably trying to remove it. I did a post a few months back showing how dents and gouges in the boss can be rectified, almost back to normal, with the minimum of filler.
I managed to get one of a batch of new ones discovered by Dunsfold (presumably in a job lot of crates that they bought) so ended up selling off all but one of my collection. I only had the broken one restored, as it was unsaleable, and unusable as it was. I will get my 'spare' done at some point. The last un-restored wheel I sold went for about £200 in typically cracked and worn condition, but perfectly restorable. I have seen some appalling ones, only fit for the skip at stupid prices.
I am sure there are other wheels that might fit, but try getting one in decent condition!
