I have a few 19 litre Corny Kegs from my beer brewing days.
Would it be OK to use these kegs for long term storing low wines, high proof spirits and feints?
I don't know the quality of the stainless steel...304, 316, 201.
Thanks in advance to all replies.
Cheers,

Cornys are well used in the aging and storing of spirit mate, go right ahead.

This is what I do

You may want to replace all the o'rings with silicone one's as well. You can buy silicone replacement sets and the kegs are great for storing / ageing.
I should try & fit one of those taps that Stig mentions but I'm yet to work out how to fit it. I saw a post where Stig said he had a mate with skinny arms who could put his arm right into the keg.
I put one in a 50L keg but needed to remove the element so I could install the tap on the other side & tighten it up through the element hole.
