Gliding aficionados - help wanted

A couple of years ago I was given a large supply of aircraft colour slides, unlabelled,  which included the four

below. I have disregarded these until now, but feel they could be included in the aircraft showcase. What I need to know, if you can help, is the make and model of these gliders - I know nothing about gliders. I am guessing the first two photos are the same machine.

GG looks like a Bocian to me.. wood construction, long narrow wings and the elevated rear seat are markers.

“28” looks like a Mini-Nimbus (Janus)

Bocian, Janus and ask21 I think. 

Yes...I couldn’t make up my mind in no.3 even though I flew one a bit. Long while ago now, 40 years.

Thanks, folks.

Not a Bocian... wrong tail, cockpit and cranked wing. Not sure what it is though

Did a search on the tail no PL90 on the fourth photo and came up with Grob G-103A Twin II Acro.

I think the first glider is a french aircraft called a Wassmer Bijave, the second is a Schempp Hirth Janus and the last is a Grob 103 Twin 2.

Yep, here's the link https://en.wikipedia.org/wiki/Wassmer_WA-30_Bijave

Pretty certain the last one is a GrobTwin Astir 2

Thanks Mike

i flew the Bocian when instructing at Euroa but that was 40 years ago. It gave an audible sigh when you entered its very gentle spin.
