Is it Optimus 200 in general, or these early ones in particular that's on your list? If you just want an Optimus 200 in general, they aren't so hard to get hold of. But the specimen in this post is an early one, so not always so cheap when on sale.
To start with one I would not care if it's an early one or from the 50s or 60s or even later. I have several Px 821 which I would like to compare with an Optimus 200. Thank you Carlsson for mentioning that they are around. I'll have a look. Matthias
Is now one for about 400 euro and another one in brass for 280 on sale (it is a buy now announce). Best regards, Frank
@LatMag49 I have a couple of spare 200s at home also a couple of 821 babies. Send me a PM and maybe we can organise a swap.
