Thank you.
I missed that in my search.
Any upgrades that need to be done? I mean I want to keep it stock but are there any issues I need to address?
The three finigered barrel bushing (aka collet bushing) has a reputation for breaking, although I've never known anyone, or read a posting from anyone that actually experienced it. Its always someone who had a cousin who knew somebody,,,,,,,,,,,, Anyway, one upgrade might be to replace the collet barrel bushing if it still has one with a collet bushing that hasn't already been changed The pistol will be more accurate, but whether your personal shooting skills could take advantage of that are known only to you. Refinishing would enhance the appaearance, but would lessen its value.
The stock sights are awful and that is probably the most frequent upgrade, although again you lose the "stock" claim. Safe with extended slide stop, thumb safety, beavertail, etc. Grips can be changed out and you can keep the old ones to reinstall to recover the "original" status.
A trigger tuning might be in order by a competent 1911 smith and you'd retain the "original" status and have a much nicer pistol to shoot. Thats about the only "improvement" you can do that will enhance its performance and not degrade its value.
Unless you send it to a Custom Gunbuilder for a total makeover ($2K+), anything you do to it peacemeal will lower the value over its current status, or at the very least not enhance its value one bit––on a resale. If these changes/upgrades make the pistol more pleasurable to shoot, then its your pistol and you should go for it.
