I apologize for hijacking your post with an unknown pear. Hopefully we all continue to remember your original goal which was a cold hardy Abate Fetel style pear. Here is a video of Abate fetel at their best for anyone not familiar with the variety https://www.youtube.com/watch?v=RF8HraBLYtE. It is a difficult pear to match.
I see very vague mention of the pears you mentioned in some old NAFEX threads. They appear to be Canadian pears http://www.ibiblio.org/london/NAFEX/message-archives/old/msg00010.html & http://www.ibiblio.org/london/NAFEX/message-archives/old/msg00020.html. Another mention of the series http://cjoliprsf.awardspace.biz/Documents/SavignacPears96.pdf & http://www.cjoliprsf.ca/Documents/PearArticle07.pdf
Finally found them and they are similar. Some of these are a cross of Zuckerbirne x Clapp Favorite or Kurskaya x Flemish Beauty which potentially would be high quality pears. The attached descriptions should help you identify your pears Jocelyn. The photos are not the best but ripening times are descriptive..
Thank you Jocelyn for bringing up a couple of these varieties because I was unaware of them. At least one of these are virus infected so be aware of that if you request the scion wood from the usda and make sure your requesting the ones that are not infected. I combed through the main catalog to find them http://www.ars-grin.gov/cor/catalogs/pyrcult.html. You can see some similarities in these pictures on the USDA website https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?accid=%20PI+617571
This was another picture they listed "Image for: PI 318838 - Scanned black & white figure from F.S. Howlett. 1957. Ohio Ag. Exp. Station Research Bulletin 790.

The leaves on my unknown yellow pear shown below are similar and pears are somewhat similar. These additional pictures below may help to identify my pear.
If your trying to learn more about the Canadian varieties then you will also be interested to know in 1947 they sent some pear crosses out to be grown out such as savignac ronde verte which is listed here http://www.hardyfruittrees.ca/catalog/pear-tree/savignac-ronde-verte-pear-tree-zone-4-flavourful-disease-resistant-pear
. Researching these pears could lead to the discovery of many others. The unknown pear I have may in fact be an unknown cross from that series. A pear called Savignac can be obtained here in the U.S. http://www.sln.potsdam.ny.us/pears.html
. I find it interesting that anyone would confuse the old fashioned kieffer with this variety but when I purchased my tree from the Arbor Day Society that is what they sold the tree as being. One notable characteristic you can tell about the pear I grow by the photos is it's notably long stem. I will do my best to make sure this little yellow pear does not wind up being another exceptional pear lost to time. Of the above photos the pear 170084 is the closest in this series of pears to a match with my pear. The others seem to have a shorter stem or rounder form. They do appear to possibly be it's siblings. My pear has thorns when it's small if that helps with identification. I do have a possible theory as to how this supposed old fashioned kieffer came to be sent to me which is it may have been a rootstock that's graft failed before they sent it to me because it did not show a graft union. Moe was actually used in Canada as rootstock. I suspect that's why my pear is compatible with everything I've tried to graft it to and it looks like I was not the first one to notice the ease of compatibility http://lists.ibiblio.org/pipermail/nafex/2009-January/033955.html
. Additional testing was being done as you can see here "Pear. The following seedlings are undergoing extensive test: 0-291 and 0-292, both from Winter Nelis x Bartlett; 0-301 (Menic x Winter Nelis); and 0361 (Miney x Phileson). Grosses involving the hardy variety Karl Sabioski, Bartlett and high-quality 0-291 were effected in 1950. " - https://www.cabdirect.org/cabdirect/abstract/19561603667
. These were pollination requirements "Author(s) : HUNTER, A. W. S.
Book : Progress Report. Horticultural Division, Experimental Farm Service, Canada, 1949-53 1955 pp.20-1 pp. ref.bibl. 3.
Abstract : The pollination requirements of the pear varieties Enie, Menie, Miney, Moe and Phileson have been studied. Enie, Menie and Phileson were each satisfactorily pollinated by any one of the other 4 varieties. Miney gave a satisfactory crop when pollinated by Enie, Moe and Phileson, while Moe was pollinated satisfactorily only by Menie and Phileson. Phileson, and to a lesser extent Enie, Menie and Miney were self-fertile, while Moe was self-sterile. All varieties were regularly capable of producing an appreciable quantity of mature fruits from emasculated but un-pollinated flowers; these fruits were seedless. Seedless fruits were also produced by self-pollinations, by Menie pollinated by Miney, and by Phileson pollinated by Enie, Menie and Miney.
