Ithaca Model 37 Schematic

WHAT years of production???

all

To add to what twistedoak said from 1937 to present.

the only really big internal difference between the new ones and the old ones is part 21. the new ones is a pin and the old ones is a really tiny screw. and I have gotten to be a really big fan of that pin.

otherwise the schematic applies to them all

Best I can tell the screw was changed to a pin in the mid 70s. I have a 37 from 1974 with the screw, and a 37 from 1977 with the pin. I think that the pin idea was a carry over from the model 51. If you take one of them apart you will find like pins. It was most likely cost savings. Saving time from threading the hole and making or buying those tiny screws. I have never had a problem with one of those screws and I sure hope I don't. If one of those got stuck it would be a bear to get out.

Also keep in mind that a few of the parts like the lifter would be different (longer) for a 3 inch gun.

I forgot to add unless you find an untouched gun with the serial number starting in 38 then part 13 would be different.

the hammers can either be spurred or unspurred too
that and the tang on the trigger blocks are 2 sizes

That's right, I forgot about the hammer,

I don't know if it was cost savings or not, but I like that pin over the screw. You can work it loose alot more easily that you can the screw. I've had to feather a couple of them out because some yahoo tried to take it out using god knows what. And this will be one of the VERY few times you will ever hear me say I prefer a pin over a screw.

What changed in the carrier, Chuck?

It wasn't much of a change, spurs on the carrier. It was supposed to help with ejecting the spent shell. The carrier was changed back. However, you will find spurs on the shell carrier on several guns made after that.

There was something else about the 38 serial number range guns. I will have check on that and get back.

hey thanks for the info, Chuck!

the carriers hes talking about were basicly all recalled ,and they were replaced with the standard carrier.

if you find a 38 with the spurred carrier its a pretty rare piece,as most were retrofitted.


also on early (real)early m37s they used only 1 extractor (top i think) and very quickly a 2nd was added all singlr extractor guns were recalled and retrofitted the 2nd extractor.
and early m37 with a single extractor is also extreamly rare to find

I am having a vision of what spurs on the carrier could do to paper hulled shells.....

Actually there are other differences in the guns marked with the 38 prefix (1975). besides the carriers
The shell stops were different and the action bar was notched to allow this to work. The new system was supposed to eliminate the hand fitting required.

This didn't work and all of the guns with the 38 prefix were recalled and repaired. If you should find one that has not been touched it is very very rare.

The topless extractor models my friend from Pennsylvania is talking about is is really really early. A left over from the parent gun the Remington 17. From what I have read there is only one left serial #2023.

I have often wondered why Ithaca had problems with out the top extractor. My model 17 has always worked fine. I wonder if it was because the 12 gauge shell is bigger and harder to extract (the 17 was made in 20 only. Any guesses?

Well, a 12 ga shell is heavier and that extra weight could cause a shell to drop prematurely. the other one could be swollen hulls which might cause the extractor to slip

I don't know serial #2023 dates to 1937. So the double extractors is an improvement on the original design.

Their where 3500 guns made in 1937 starting with serial number 1. I have 2 first year production guns one in the 7xx range and one in the 25xx range. Both have been "updated" to the double extractors. From time to time I come across other first year guns on Gun Broker and they all seem to be updated as well. My guess is that they most likely updated all but a handful of them.

I would agree, like I said before from what I have read (Mr Snyder's book) only the one remains with the single extractor. There could be more its anyones guess.

If there is another I would bet that a) you could auction it off for a very healthy figure and b) the person who would own it, would have NO idea what he has.

along the thought of people and guns they have no idea about

i think about how many gorgeous guns have been melted down in them "guns for nike sneaker " deals
that PDs often hold

i just noticed my 75 starting with 371 has a spurred carrier in it

I know exactly how you feel. For the sake of not opening another can of worms I will refrain from further
comment.

If memory serves the 38 prefix dates to 75. Ithaca used the old style or spurred carriers through out the mid to late 70s. Remember, the company was going through bankruptcy around this timeframe.

Besides, most factory shells were plastic. So the spurs were not really to much of an issue.
