Do you mean large cassette, or do you mean cartridge? Do you mean
the 1/4" cassette format (for which no commercial machine was actually
released) or one of the 1/4" continuous loop cartridge formats (which
look like broadcast carts but are larger)?

When you say 'commercial' are you excluding consumer machines? These
weren't common, but they did exist. My dad had one in the late 60's
that he bought used. It had 1/4", mono, double-sided, double-hubbed (R
to R) cartridge, roughly seven inches by maybe five inches. Tape ran at
3 3/4 ips.

I'm not aware of a stereo model, but would imagine it to be half-track....

Further research indicates that RCA did indeed introduce the format in
stereo (1958). Speed for prerecorded cartridges was 3 3/4, but some
recorders also had a 1 7/8 ips option. Word is that the stereo machines
are now rare and somewhat expensive. There's a mono(?) version on eBay
right now, starting bid: $29.95
