Vintage unknown large mirror school bus? semi? big truck? 17 inch side view?

Description

Here is a mirror.  It is used and shows wear as you can see.  I have no clue what it fits, determine fitment for yourself based on the part number/pics only.  I can get you any measurements or anything like that that you need as well.  It does show some wear, and is dirty; see the pictures.  It could use a good cleaning to look its best.  Let me know if you have any questions.  Please look at the pictures prior to purchase and make sure that everything looks like what you need.  There are no returns, so make sure you ask any questions or figure out any info that you need prior to purchasing.
All of these items may have
scratches, nicks, could be dirty, etc.  Use the pictures to judge condition farther.  Sold as is.  Shipping is to the lower 48 states only.  I will answer all questions.  I take feedback seriously.  Please leave me good positive feedback and I will do the same for you.  Check out my other listings!
Note, handling time on this is 5 days.  That is a maximum number.  If you want a more exact time of when I could get it shipped, please message before buying and I'll see what I can do.  Thanks
