Here we have a NOS Door Lock or Cargo Lock with 1 Key for Vintage Cessnas. We are not sure what model this goes to but we are sure it's for old Cessnas. We did provide measurements (see images) so you can compare it to what you need to replace. We have other NOS vintage Cessna locks and lock sets that are listed.
Please note that we have a few of these (all keyed differently) and the one in the image may not be the one you get.
If you have questions or need other measurements or images, please let us know.
