I wouldn't consider a genuine Fw190 or Me109 practical for the Collings Foundation to tour with. I believe the DB motor is only good for 100 hours and it's a safe guess that the BMW would be delicate to operate as well. (Flying Heritage is only flying their Fw190 one day this year, and they have stated that the BMW is temperamental.) Unless they move them around on trucks, both would be expensive to operate and accumulate wear and tear. So the other option is to leave both aircraft at one location.
I posted a question on a German aviationforum. regarding TBO´s of DB engines. A forumite, "78587?", involved with "Messerschmitt Foundation", wrote the following:
Part Overhaul: every 100 Hours, Main Overhaul: every 200 Hours, maximum lifetime: 600 Hours, as by the original DB-documents and (original) approval by German aviation authorities.
