Early (1st Ser Block) Underwood can be found with just the one forward notch on the receiver rail.
Do we know about what serial range they went with the 2 notches?

Also I believe (IIRC) they always used the rear square cut on that rail.
I think I've seen this rear mill cut in narrow and wide.

Did the width of this mill cut go from wide to narrow..... or narrow to wide ?
When the 2 slide rail notches became the norm, did it coincide with the timing of changing the mill cut width  ?

I don't want to wander in to the Sub supplied receivers just yet, trying not to complicate this any further. Unless the changes occurred 'Because' of the Sub supplied receivers.

I hope this makes sense.

Appreciate any input,

Sounds like your receiver is an Inland

I misread and thought Charlie suggested it was a round notch. My error.

Inland supplied the first 100 receivers used by Underwood and they had one notch and round detail.

According to CCNL 127 Underwood had one notch to about 1,428,000 with the first reported double notch at 1,444,xxx

there is 2 other newsletter on receiver construction features that shows Underwood having 1/4 to 5/16 inch distance early in the first block. At about 1.441 up it went to 5/8 to 3/4 of an inch

So I would say the double notch and end width came about in the same time period.

Wayne, that was the highest number on the 100 receivers Underwood received and renumbered from Inland.
ccnl 259-3

I somehow thought Charlie was saying round vs sq. cut making me think Inland.

Too add: Underwood produced the first block then worked on the the 4 million block. Before finishing the 4 million block they moved onto the 2 million block (Underwood and subcontract) then working in the 6 million and finishing the 4 million block.

Does this makes things easy?

the additional notch was a tooling hole to get the cutting bit in and out. It made manufacturing easier. I guess NPM never got the memo.

The wider width saved time and tooling wear.

Hi all.
I don't know if it is discussed in any of the news letters, but I noticed an interesting thing regarding Underwood subcontracted receivers made by Universal Winding ('W").  They are double dismount notched, but have the "earlier" narrow 1/4 to 5/16 inch distance milling space to the rear.  I have not found a single Universal Winding that is not the narrower space.  I have looked at 7 different "W" receivers with s/n from 2459781 to 2484328 and they are all narrow and double notched.  I have found that all of the other subcontracted receivers from Intertype, United Shoe, and Singer all have the wider rear milled section.
Does anyone know if this has ever been noticed or discussed?  I guess maybe Universal Winding was provided with the earlier milling template to make their receivers, possibly?  It is kind of a cool variant because the Winding serial numbers in Block 2 fall after the Intertypes and before the United Shoe and Singer.

Chad, Back in 1981 in CCNL 59 there was a chart of receiver construction laying out the notches, rear leg length, the slide cut (round or taper), and the distance to the rear.
the distance is listed as 1/4 to 5/16 for the winding receivers and as you point out the other subcontracted receivers for Underwood are in the 5/8 to 3/4 range.
