There's several web sites showing folks' resolution tests (LP/MM numbers)of all sorts of large format lenses. But this one's not on any I can find.
If anyone's got decent info on this lens' resolution numbers, please let me know where. My lens seem pretty sharp, but I don't have a good way to evaluate its resolution. |

Buy a USAF-1951 target and test yourself. Edmund Optics sells them.
Why bother? If it shoots well enough for you, that's all that matters. |

| It's a very good lens. I just wanted to find out how it stacks up against other 135mm large format lenses. |

And when you know, what will you do? Be happy? Brag? Be unhappy? Replace it?
You already know that it is a tessar type, has to be stopped down to get good detail in the corners. If you can't live with that and want a 135 your best bet is to get a modern plasmat-type 135. Not a convertible Symmar, something more modern than that.
Good luck, have fun,

Are these four reasons the only choices I have? |

| Oh, no, there are many more. But they collapse to two. Continue to use, replace. |

That's part of "replace," Henry.
Why don't you offer him a superior replacement in trade? |

It's negotiable, but I prefer an outright gift! Replacement is up to the giver  |
