Very nice Kastrup Glasswork items you have found there.
Do not have the catalogue on your items, but do have this info:
The cyl. vase shape do appear in the Kastrup catalogue Marts, 1962 for Capri Line Blue design Jacob E. Bang in 1961, here the vase is 18 centimeter item no. 32613, 24 centimeter item no. 32614 and 30 centimeter item no. 32615.
No jug present in your shape.
The cyl. vase shape do also appear in the Kastrup catalogue for Green Line May, 1960 design Jacob E. Bang in 1960, here the vase is 35,5 centimeter item no. 7161, 25,0 centimeter item no. 7160 and 20,0 centimeter item no. 7162
Also your jug shape appear in the hight of 26,0 centimeter item no. 7169.
The cyl. vase shape do also appear in the Kastrup catalogue for Opaline Line May, 1960 design Jacob E. Bang in 1960, here the vase is 20,0 centimeter item no. 7196 and 25,0 centimeter item no. 7195.
No jug is present in this range of your shape.
None of the shapes are present in the Kastrup catalogue for the Nightblue Line, May 1960 nor the Black Smoke Line also May, 1960
I will estimate that your items must be after these rather large series in different colours and properly a smaller pick from these series in a new colour in the end of 1960th. but it would only be my guess in lack of catalogue documentation.
Hope you can make use of the info.
