<div> <font size="3">Jack, I believe the significant difference is in the header rail. The TR4A uses Herald-sourced "over-center" latches, while the TR6 used the "bayonet-fix" pin with lever.</font><br>

Are TR4A top frames and header rails interchangeable with TR6 top frames and header rails ?
</div>
