Nepal Cover -Please Help ID Two Stamps

Hello, This is a nice registered cover from Nepal. It was posted from Katmandu to Berlin. I am not sure of the date it was posted though the stamps are from the 1960's. I am having a problem identifying the two stamps in the top right corner. I have looked over abd again through the Nepal section of Scott to no avail. I have identified all but those two.Can someonr possibly identify them for me?Many thanks
David

I don't collect covers, but I have to say, very nice cover!

The 2 stamps are Nepal 110 and 113 in the Scott catalog. Both stamps were issued in 1959 are part of a set to commemorate Nepal's admission to the UPU.

Thanks again khj, I probably overlooked them 10 times at least.Now maybe I can get rid of this headache.
Thabnks again
David
