Help Identifying M1 Garand IHC Receiver

[Panhead57]

I own a IHC M1 that I purchased from CMP in 2005 that I believe is a LEAD rebuild. The serial number is 4,550,6XX. It has an LMR barrel dated 4-53, and all the major components (Bolt, trigger housing, op rod, hammer, gas plug, etc.) are IHC marked. The stock has a circle "P" in front of the pistol grip and the number "3162" in the barrel channel. While this rifle has a postage stamp style receiver marking that reads "U.S. RIFLE / CAL. 30M1 / INTERNATIONAL / HARVESTER/ 45506XX", the side of the receiver is marked "D6528291-E" and "LEAD 10-64".

From what I can find, receiver drawing number D6528291-“E” was assigned to HRA rifles.

Has anyone ever come across a IHC receiver marked like mine?

May shed some light on yours. https://forums.thecmp.org/forum/cmp-sales/m1-garand/157933-ihc-lead-rebuild

HRA is known to have supplied approximately 4000 receivers to IHC at the tail end of production.
HRA stamped the serial numbers and the drawing number but IHC stamped the postage stamp style heel nomenclature.
These receivers were used in production from approximately s/n 5,223,034 to 5,217,065.
There is a range of IHC receivers produced in house starting around 4,51X,XXX to around 4,62X,XXX where the drawing numbers are D6528291- letter code.
I have seen receivers with letter codes ranging from A to F.
Yours fall within this range.

Thanks for the link to the article, however, it doesn't mention anything about an IHC Receiver with drawing number "D6528291" followed by an "E".

I think I lucked out with CMP on this one. It's still in as originally rebuilt condition, and I'm pretty sure the LMR barrel is original to the rifle. Additionally, it looks like all the other major components are correct "IHC" items. I have other M1's so I never shot this one.

My main concern is that none of the IHC M1 source documents I can find show an "E" suffix receiver.

I'm hoping that some M1 enthusiasts may be able to shed some light on this.

Another source may the the Garand Collectors Association. I havent been a member for more than a year, but thier magazine has some really great information and history.

Nice rifle.
Not trying to rain on your parade but the chances of a rifle going through a rebuild and coming out with all correct original parts is 0.
You rifle has likely been "corrected" at some point.
The CMP is known to swap parts around to make rifles correct.

I have other M1's so I never shot this one.

One did in post #3...

This is where the info in post 3 comes from.

Lange Carabine - thanks for the info about HRA receivers. I didn't say that this rifle had "original" correct parts, just "correct" IHC parts.

If the rifle was corrected, it must have been done before being received by CMP or by them since I haven't touched it since I purchased it directly from CMP.

I find it interesting that HRA's receiver drawing number for Jan 1955 - Dec 1956 serial numbers 5488247 - 5793847 in one source document is the same as mine - D628291-E.

Do you think it's possible that HRA may have sent some receivers to IHC in 1953 or 1954, when IHC was making 455XXXX serial numbered rifles? I read somewhere that for receivers that IHC received from SA and HRA, IHC would mark the receiver heel, but SA or HRA applied the drawing numbers on the receiver legs.

Still, there's little to no chance of it going through rebuild a Letterkenny and coming out with all IHC parts.
A late 64 rebuild would've had at least some SA parts.
Do you see any Letterkenny markings on the stock? Like an orange triangle with LE inside.

What grade is it according to the CMP certificate?
CMP got them direct from the U.S. Army AFAIK so if it has been corrected and you didn't do it it was done at the CMP.
Like I said, the CMP is known for its parts swapping.

Yes, that is interesting.

I can only find where HRA supplied approx 4k receivers right at the tail end of IHC's production.
IIRC, SA supplied around 1100 finished receivers(including IHC markings and nomenclature) and a further 800-900 unfinished receivers( except for drawing number with a "42" or "43" code iirc) to IHC.

I'll see if I can find the certificate.

Yes, that is interesting.

Your IHC is exactly like mine. I can't find any reference to an IHC receiver drawing number ending in "F".

Here ya go

 

[Panhead57]

Serial Nos. 5104106, 5111653, and 5151117 with Drawing Numbers ending in "E", "Y", and "L" could definitely be a receivers HRA provided to IHC towards the end of their production run.

But my Serial No. 4550694 with Drawing No. D6528291-E is still a mystery to me.

Something to keep in mind with IHCs- they had more production variances, start/stops,parts from other suppliers and other oddities than any of the manufacturers. Not uncommon to find later serials with original earlier barrels for example.
Another thing of note (and pertaining to this thread) are these drawing/lot #s on different serial ranges. IHC didn't use a first in, first out order of production. Not uncommon at all to see late late production with much earlier drawing numbers/lots. Parts were pulled from storage areas as production needed.

They are outside the known s/n range for HRA receivers.
Mine is a 5.05M non rebuild mixmaster. Mostly IHC, stock, safety, front sight, gas cylinder, lock, and lock screw are SA the rest is IHC.
Has an "S" letter code.

Why should IHC Armament be any different than IHC Automotive? I had a 1966 Scout with their slant 4 in it. When I tried to replace the worm gear from the speedometer to transmission, there were 12 different options with very poor pictures to choose from. Not only that, when the magic smoke left the electrical system, we discovered that all of the wiring harnesses were done in Red wire. Two other samples were all done in Yellow or Green respectively.
