What are my options?

[miscreant]

Okay, I've had a suit of armor made for me, late 14th century, and due to the length of time it has taken to get it made for me and the fact that I am still waiting on the legs 3 1/2 yrs later going to the armorer with my problem is not an option.
Last night I put on the arms and the spaulders, (yes, I am a procrastinator) and found that their is a gap of about 4 inches between the upper cannon and the spaulder. Also, around the wrists of the lower cannons, I am unable to twist my hands, they are too tight. Maybe I gave wrong measurements, but the other two suits that I have and ordered at the same time fit perfectly, so I'm not certain about the measurements.
Any way, I am not an armorer and don't have any types of tools for working with metal. So what are my options?
1. Should I just sell them off?
2. Should I find someone to work with what I've got?
-Who?
3. Should the upper cannon be extended or should the spaulder be lengthened?
4. How should the wrist be fixed? An inch could be taken off and that would help some.

Any input would be greatly appreciated. Thanks.

What will you be using all this armour for?
A gap between the upper cannon and the spaulder isn't uncommon in 14th century armour. The Churburg #13 harness doesn't have associated spaulders, and its rerebrace only comes part way up the arm.
It's tough to make the wrist larger, but trimming the end wouldn't be too tough. You could probably do it with a grinder if you had to. Another option is to do some slot articulation so the vambrace will rotate. It's possible that is what your armourer did, and the articulation is just stiff.
If you can show us the harness it might be easier to see what to do with it.

The Churburg #13 harness doesn't have associated spaulders, and its rerebrace only comes part way up the arm.

Note that CH S13 does not have an associated shoulder defense at this time. It probably would have had shoulder protection. CH S13 is not entirely complete. For instance, the gauntlets have found themselves away from the harness. It would not be impossible that other elements may have, as well.

Possibly true. A very large percentage of illuminations of late 14th century armour have fabric covering the body, so it's hard to tell what form the shoulder protection typically took. It's possible that the shoulders were protected with padding, as King Renee suggests ~50 years later, or that there were spaulders more like we see in Prince Edward's effigy from a couple decades before. Or maybe they were OK with an avantail and a surcoat. I'm not sure I'd go that route against a poleaxe, but it would offer some protection.
