You have a full set of targets. The hunt may be long but it will be good.
The 5508 may be the one you will have the most choice on. The 6538 and 5510 there may be a dry spell. But if you keep your senses sharp all are attainable.
We all know this hobby is about being patient. Look at these old watch 20,30 and 50 years and and they are still patient with us.
