20x110 and 30x113 dummy projectiles

[Nabob]

Hi,
i am looking for info on these two rounds.
base of the 20 mm is steel, 30 mm brass.
There is one like that in this thread
http://www.bocn.co.uk/vbforum/threads/95615-20-x-134-mm-Dummy?highlight=134+dummy

I also have a pics of a 20x139 round that are probably from bocn.

Same style of base and a groove on the body.

Thanks, Bob
