Anyone know what head this is? It looks like an m head but no serial number and it has extra holes with Allen screws threaded in.

OK, to post a picture click on the icon of a painting of a tree right above the box you type in, after you choose file you need to click the upload files.
Picture icon is bottom row, 4th from left on my computer

It looks like an M head to us... at least from that picture.

You can also do it manually by typing [.i.m.g] and [/.i.m.g] before and after the URL. You have to remove the '.''s. I had to add them to make it visible.
In Flicker you have to use the "share" and bbcode to get access to the image URL.

see if these pictures show up... one of them is a typical m head casting.
what are those 3 extra allen bolt holes for???? Ive never seen any m head with them. And theres no serial number lug on the side of the head.... Did bridgeport make several variations of the m head?

It's an early M with the quill sleeve missing. The first of the M's were slit top to bottom so that a shim could be removed to compensate for wear. I had a complete one--- #236 as I recall--- which was dated by the fellow at the Bridgeport CNC school as 1938. Serial #'s were stamped on the top of the aluminum belt box

Herb,
That's interesting to know. That makes sense. I thought it might have been another oddball head. I've seen a few unusual m heads on the internet with some interesting features that I never new existed. I think I'll strip some of paint and look for that slit. So I'm guessing the early heads did not have a stamped serial number anywhere on the iron casting, only on the aluminum top housing. Well, I appreciate that information? Thank you

No number any other place that I know of. Perhaps "shim" wasn't the best word- the piece is about a quarter inch thick, and apparently the idea was that you would dust off a thousandth or two from this with a surface grinder if the spindle got loose.
Clean off all the crusty paint, and it should start to make sense.
Glad to be of help.---Herb

Here is an early Bridgeport catalog, on ebay, showing the early head.

I bet you will find the slit is packed
with wool felt and painted over many times.
Does Bridgeport #1 at the American Precision
Museum in Vermont have the split? I know
the heads were made before the machine.
