I just use what i have left over from my accumulation of N-scale std. gauge.
For the imaginary era and world that i model,
plus with the overhang, they're not really all that noticeable.
One thing i would like to do though, is go back to the old Rapido type coupling,
with their wider gathering range then the more to scale of N-std. gauge couplers,
that when i was in N-std. gauge i ended up replacing almost all of them with.
Not sure what i did with all of the ones i had. i can't believe i just tossed all of them.
that's not like something i would do. but they do seem to be AWOL.
