Bill,
The telescopic transom ladder on your bathing platform looks suspiciously like a bog standard 4 step telescopic ladder marketed by Plastimo.
Try calling Frank at Force 4 in Chichester (01243 773778). Apart from being the manager (i think) he owns a Bav 36 and has a wealth of knowledge on what fits where on most Bavarias so he may well be able to help. He has sorted me out on spares a few times.
Also very good at sourcing Rutgerson spares for blocks and hatches.
No connection, just a happy customer.
Of course if he can’t help you can always ring Steve at Clipper.
Cheers
Rick
