I'm starting to think my best option, to keep it French, is to see if I can knock down a 6000 or 610. Like GB, I always seem to get outbid on them and can't justify $125+ for an SLJ 5000. I'm still thinking there must be a way to build and adapter plate for a Nuovo Record, though, a'la the Crane above, but I suppose if it was easy someone would have done it already. In my sometimes too fertile brain I'm even looking at the possibility of turning a custom top pivot bolt that fits the NR, threaded on the back side to accept the Simplex shoulder bolt. I have the machines, but probably not the skill, and then there remains the pesky question of the stop tab.
