ISO: Di2 Components and Ultegra Shifters

Looking for below; PM if you have anything available with a price!

Di2 Internal Battery
Di2 5-port Junction Box (EW90-B?)
Di2 Wireless Transmitter
Any Ultegra shifter with the top button (think R8050 and onwards?)

I have both a complete Ultegra R8050 mechanical and R8070 hydro groupset available if that’s something you might be interested in. Sounds like you only need a few parts tho…

I have a set of R8050 shifters if you’re still looking.

Still looking around for these parts; how much for the R8050?

Apologies for the delayed response. I’m supposed to have two sets somewhere–one beat up, the other fine, but somehow I’m only finding one from each. I’ll send over photos and a price once I get that sorted out.
