Monarch Lathe Identification help

I recently got an older monarch as well, and the previous owner has no idea what model number. The ebay listing with a couple of pictures is here: Monarch Engine Lathe 20" x 42" with taper attachment | eBay.

I checked the lathe ways, and found a lot number stamped in, along with inspection information. The lot # is B2375. Unlike the picture in the PDF in reply #3, the serial number is parallel to the vee, instead of perpendicular, and doesn't have a machine number.

Anyone have any ideas what model of lathe this is?

B suggests 18" or 20" and 2375 says 1929. Such designations are left over from the Model A (14 and 16") cone head era - before later and more familiar designations became the norm

VM has this from October 1928 - top speed is 311, and it has a 3 1/2 - 4 threaded spindle nose - not something you will find for sale when shopping for more spindle tooling or back plates for a differing chuck (and since your machine is from the next year it may instead have their proprietary flanged spindle nose - which is equally odd ball)

I have recently acquired a churchill redman c12 lathe. But its identical to the monarch c12 machine. I am not sure if it's a monarch. 20191010_164217.jpg

Usually the Serial number is stamped on the far top right end of bed just behind the front way in the clearance area. If you find it let me know as I have several serial number books I can look up when they made the machine. Looks like a 1930's machine
I have a model a monarch and in search of information on it serial is 187 b

Good day all. Apologies for resurrecting a dead thread but I figured this would be the most efficient method to ask my questions.

To preface, I am a neophyte when it comes to most things, machining being apart of that list.

Recently, a monarch lathe has come up for sale near me and it's the spitting image of the one pictured in the op's post (although a bit larger, I'm guessing in the vicinity of 16×70 although I have not viewed it).

My question falls into the catagory of 'if you need to ask you shouldnt...' but I'm going to ask anyways. Upon asking the seller if there was any tooling to go with the lathe, the answer was simply 'no tooling'. From the pictures I have gathered it has: a 4 jaw chuck/faceplate, tailstock, a toolpost of sorts and a three jaw chuck which im thinking didnt orriginally come with the lathe. I realize this is a 1920's-1930's piece of machinery we're talking about but I'm wondering if things like steady rests, centers, additional tool posts etc. Still exist for these machines? Are the ways of later machines the same or similar enough to use those accessories on the earlier machines? Granted all of these things can be made but I think I've made my point.

I am in the beginning stages of setting up a machine shop on our farm. For the right price, I'm thinking this could serve as the bigger lathe barring it looks good in person. Certainly not set on it, it's just something that came up for sale and well, I do enjoy an adventure.

Oh and apparently it does run!

The tailstock should be Morse taper which is common. Steady rest may be hard to find but you can modify the base of another steady rest of a similar swing. Tool post can be fit pretty easy. The mounted 4 jaw is a lot more versatile than the 3 jaw.
It's a good workable piece of iron depending on condition.
Run it through the gears and educate yourself on what to inspect. It's all here on P.M. or on Utube.
It would benefit you to start your own thread unless you are only wanting these questions answered. It's my guess that you will want more information if you buy it. Adding on to old threads will get fewer responses.
You're in the right place to learn. The Monarch guys here know these machines.

Big Monarch Lathe ?

Just picked up a big Monarch lathe and am curious about it .

On the tailstock end ,right side top it is stamped with inspectors mark and CBB3438,and a U. an anchor and an S.

On headstock cover is an oval brass tag with 251 and underneath that is 006377 and U.S.N. stamped under that .

It is 18" from center to ways and around 58" between centers .

Any idea as to model and vintage ?

Thanks !
This was a lathe built for the U.S. Navy. This would be made in the 1930's. Does it have a "flame haden" bed? Contact Monarch Lathe for more info.

Member Reaperbond revived this old thread from 2020 yesterday adding on a different subject. Post 27 about a potential purchase.
Bubba45 was last seen in 2011. New members have added onto this thread twice.
It makes following the subject confusing.
Reaperbond made a good post and photos [post 27] but resurected an old thread.
