What Kind Of Postmark Is This?

Hello,

First of all, I will show the postmark in question:




It is on this cover:



I think it is not a machine cancel because the four bars on the stamp are not horizontally in line with the postmark. At least that is how I see it.
The letters "R.F.D." in the first row are new to me and I do not know what they mean.
I hope someone here can give some information about this postmark. Also to literature, in which I could find something about it.

Oh yes: still the back of the letter:




Have a nice weekend!

RFD is abbreviation for Rural Free Delivery.

What a great cover. The railroad cancels are fantastic along with the stamp combo. Seems like the 2 cent stamp was paying homage to the railways? Great history to the rail lines involved including an owner of the Island Pond Railway in VT being lost on the Titanic. Where may I ask did you find this?

@rogdcam
thank you for your "praise" for this cover!
I bought this cover April 7, 2022 at eBay.com - price: medium in my opinion (maybe cheap?). I actually bought it because of the "Special Delivery" stamp. And am not so happy because the right stamp is cut.

I have to add: I also bought it because of the "Clerk Dater" on the back.

@khj
thanks for the explanation of the abbreviation. And for the link to the other threat. Very fine covers!
Of course, I immediately looked for information and quickly found it. This service was completely unknown to me until now.

It seems to me that I was wrong in thinking that this was not a machine stamp. I have the booklet/book by Hanmer on the early machine stamps. This one is not found there exactly. However, I have found similar postmarks from "Columbia" there (especially similar to #27). Are these postmarks really (at least to some extent) machine postmarks? And from the machines of "Columbia"? I know that this publication does not list quite a lot of postmarks (some of which I own).
So: machine postmarks - yes/no? "Columbia"? And is there any literature, or even cataloging, on these RFD postmarks? I'm still interested in that.

Have a nice Sunday!

Your R.F.D. postmark is made by a handstamp device, not a machine.

Harold C. Richow's "Encyclopedia of R.F.D. Cancels" is a good place to start. The listings of markings are incomplete, but he does list Danvers. You mark is the standard type. Quite common.

Add: In addition to Russ Hanmer's "A Collector's Guide to U.S. Machine Postmarks 1871-1925", you may also find useful: Richard Helbock's "Postmarks on Postcards"

@John Becker,
thanks for the hint it's a handstamp device.

Also, thanks for the references to the two publications. I searched for the one by Richow and found several. I suspect it will bring me more information that I am looking for and can use. Of course, all offerings from the US. So: high shipping costs. But I already know that.
I think I will choose the cheapest one and then order it.
By the way: there is a "2nd Edition" - I don't know if you know it.
Thanks again for the fast and good help!
