I measured hinge area on 201--it is 9 5/8". most Singer cabinets have that hinge measurement. yours is so close that it must be the same. I am member of Vintage Singers, they are very knowledgeable group & sharing. check thrift stores for cabinets. $25-$55 good price. wish you lived near me, I have quite a few nice ones. I don't recall a Singer cabinet with
that end opening, but I usually just deal in pre-1958s.
