I won these recently on fleabay for one of my Bandits, a little polish and a buffing wheel has them looking like new again.
The price paid??? $19.95 for the set, and theres no rust and no pitting on them. These sell at retail for about $60.00 each, isn't ebay great at times like this.
I picked up a set of mirrors off of ebay too. 1976, 10mm with the "S" embossed in them for $15.00!! The guy had the clutch perch/lever and master cylinder/lever listed on ebay. But in the pictures it showed the mirrors, with the "S" as well! I emailed him and asked if the mirrors were part of the sale. His reply was "All parts. As pictured". So I bought them! Now I have another set of "S" embossed mirrors and a spare set of levers!
Few months ago I got a pair of NOS "S" mirrors off of eBay for around $90. Still had the protective plastic film. And I thought that was a good deal.
From the other perspective, I have an original printed parts manual for a 1969 T350 that has the retail prices. Mirrors were $2.69 each. Petcock was $7.53. Tank was $34.18. Exhausts were $23.95 each. Front fender was $13.69.
Not complaining. They deserve a good bit for having kept NOS parts around for 40 years. Have noticed that NOS prices have risen over the last year & the prices spike up as the inventory dries up. For example, NOS T350 petcocks were about $100 & now are about $300 -- am expecting them to be unavailable soon.

You got that right 100%, some NOS 'S' mirrors were selling on US ebay just recently for about $40.00 each, BUT over in the UK a while ago, some sets were selling for upwards of 200 pounds. Market trends and of course supply of the items drives prices.
