Get an old, inexpensive, uncoated screwmount something-or-other, say an early Elmar, and an M to screwmount adapter. The uncoated lenses can be a lot of fun when used with an understanding of their limits. I have a ~1936 Rollei Standard with an uncoated Tessar, I use it a lot in the woods and it gives a lovely smooth look with excellent shadow detail, very little to no flare as long as I use a decent shade. The slight amount of veiling flare present in all uncoated lenses gets the film off the toe of it's response curve, bringing up the shadow detail - who'd a thunk uncoated lenses actually have some slight advantage in certain situations?
