I finally received my Mandler 35/2 lens today, or rather last night after I had left the office. Thankfully they managed to get someone to buzz them into the lobby. No signature on receipt obviously. That's about 2 weeks since it arrived in Sydney.
I ordered the silver aluminium LTM version, because that's all they had in LTM at the time I ordered, but that's OK. I prefer the lighter weight of aluminium these days. In fact the lens feels pretty solid and weighty for aluminium. It's quite a faithful copy of the Leica original, externally, although the silver finish is very slightly brighter than the chrome on brass of the Leica.
The lens is engraved 7-ELEMENT E39 MANDLER BARNACK-L1:2/35, in case you were in doubt, and came with an aluminium LTM to M adapter marked SPECIALLY FOR MANDLER 1:2/35 L39 PROTOTYPE 35/135 M.
It came in a mad crystal case where they glued an M back cap off-centre onto the base. At first I thought this was sloppy workmanship but I figure it's because it allows clearance for the focus tab if you insert the lens in a particular orientation. If you insert the lens willy-nilly you won't be able to screw on the case. The case has a small red circular badge with Mandler in Leica cursive script. Nice touch.
The next step is to use the lens.
