U.S. 1288a - 1813a MNH, Nice Group of Bureau Precancels, Some Uncatalogued

Description

Here's a nice group of Bureau precancels in MNH condition, several of which I do not find in the 2019 Scott Specialized U.S. catalogue. Included are:
1288a with shiny gum, untagged
1289 with shiny gum, untagged, uncatalogued as Bureau precancel
1584 with shiny gum untagged, uncatalogued as Bureau precancel
1585a with shiny gum, untagged
1596 with shiny gum and block tagging, uncatalogued as Bureau precancel
1813a with dull gum, untagged
I'm not sure what to make of the fact that three of these are uncatalogued. I suspect it's most likely an oversite at Amos and that they will eventually be included in future catalogs. I don't think they are particularly rare as I have seen others.

Update!
I found a few more transportation coils to sweeten the pot a little, no additional charge (see photo 4). All MNH, dull gum, untagged.
About shipping:  If a stamp is listed with free shipping, then it and any others you purchase at the same time will also ship free.  If a stamp is listed with a 60-cent shipping fee, then it and any others you purchase at the same time will also ship for 60 cents.
If you purchase a second item listed with 60-cent shipping, then please wait for me to invoice you or eBay will charge the 60 cent shipping fee on each and every item.
A Little About Me and My Commitment to You
I’ve been a regular member of the APS for over 35 years (member ID# 130461) and I’m still a collector more than anything.  If you check my feedback history, you will find that not only is it pristine, but that I buy far more than I sell.   And one thing that really bugs me are sellers who just throw  a stamp up for sale and don’t even take the time to offer a description or a compelling reason why I should want to buy their item.  My commitment to you is that I will always provide a thoughtful and truthful commentary on all the relevant aspects of every stamp that I offer for sale/auction.  And I will give you the bad as well as the good, though I try not to sell stamps that have problems.  So bid/buy with confidence that what you will receive is exactly what I have described and if you feel it is not, that I will make the return process as pleasant as possible.  You can also expect an interesting assortment of stamps adorning your shipment--no run-of-the-mill  forever stamps or postage meter strips! See photo #3 for a sample of what you can expect.
