Yes, D1-6. When I started looking I was surprised to see that the 30"
center distance was very common for that model, and space is tight
here. Many of the 61s must have been purchased for tool room work. The
other lathe I considered was the Okuma LS, but they're rare in short
beds, and even rarer with a short bed and D spindle. I do wish the
Monarch had a hole thru bigger than 1-9/16".

Interesting. My Sheldon R15-6 has a 2.25" spindle through hole with
a D1-6 mount. I guess the bearings on the Sheldon are bigger (they look
HUGE to me!) The 6' bed on mine gives roughly 42" between centers.
I know the tailstock could be allowed to overhang a bit to get slightly
more, if I should ever need it.
