Cobra 18 Ultra Crystal HELP

I have a Cobra 18 Ultra on my bench that I am trying to fix for a friend. When I took the covers off, I noticed that it was a victim of the old corrosive glue. I was able to remove all the glue and give the radio a once over. The weather bands work great and operate off of their own crystal. The problem I discovered was the other crystal, the 10.24 MHz one had been victim to the corrosive glue. One of the legs was no longer attached and broken off at the base of the crystal, The base of the crystal was pitted as well. On the crystal, I could make out what appears to be this:

XEW (or KEW) probably the manufacture?
10.24
52PF / 31 (the first number only appears to be a 5)

I am having trouble finding a replacement. I can not find a service manual for this radio. I have found only a schematic, and the schematic only states that the crystal is a 10.24 MHz. Nothing more on the other values.
I have tried to cross reference the crystal on several sites with no luck. I have searched for several days, and have had my friend search as well. I am at a loss with finding a replacement. This radio has sentimental value to it.

Thanks for ANY help you can give.

That’s a common crystal do you have any junk pll radios

I just came back from out in the garage looking. I had two Cobra 29's (China models) that were given to me a while back. Someone let them sit in the bed of a truck in a milk crate for a very long time. Completely ruined.... I cant find them, so I guess I salvaged off of them ALMOST everything I could. "Almost" being that I did not take those crystals...…. I do have an older donner radio out there that I am not sure what it is. I think its a Connex 3300HP. Malaysia in stamped on the back. Looking at the board numbers, it is an RCI board. Could be a Superstar, could be a number of other radios too. No covers, no faceplate. I thought about taking the crystal out of that, but if the suspected Connex (or what ever it is) has multiple bands, would this work?
