Feeling a bit confused now...they don't look threaded, are a bayonet type (quite similar to my Nikon F mounts, but not quite...).

p.s. the lens info on both starts with 'P'. e.g. P 1:2.8 f=135mm MC
Adapting to Nikon is difficult, it has a short registration distance. Few lenses will focus to infinity besides Nikkors... check them before you go to any bother !

I think you will find it far less expensive to pick up a body to fit the lenses, than it will be to adapt the lenses to your Nikon.

The short answer: these two lenses are of Hugo Meyer design and manufacture and was a proportion of similar lenses marked as Carl Zeiss Jena, made after 1985, in Praktica B-mount.
The long answer: Pentacon, the company who manufactured Praktica cameras, primarily used two lens suppliers: Hugo Meyer of Gorlitz, and Carl Zeiss of Jena. Hugo Meyer was acquired by Pentacon in the late 1960s so its lenses were marked "Pentacon" instead of "Meyer" a few years afterwards.
In 1985, Carl Zeiss acquired pretty much all the optical and photographic equipment manufacturers in the DDR, including Pentacon, thus also acquiring the rights to put its name on their products. A limited quantity of Praktica cameras were sold under the name of "Jenaflex", and a proportion of lenses originally bearing the name of Pentacon were also re-badged "Carl Zeiss Jena", but with a "P" added to signify its Pentacon origin. If they are bayonet mounts similar to the Pentax K, but with three closely-spaced electrical contacts, then they are indeed for the Praktica B-series cameras.
This, of course, is to assume that you can find markings on the lenses which signify its country of origin as DDR; there is also the British wild card:
The British agent for Carl Zeiss Jena (also Pentacon) owned the rights to the name in the UK, so it was free to offer products under that name even if they had nothing to do with Carl Zeiss in terms of design and manufacture. Among such products were two series of Sigma-sourced lenses bearing the Carl Zeiss Jena name, and made to fit a number of different cameras. I do not think these "British" Zeiss lenses included a 135/2.8 though, but if they bear the markings as made in Japan, then these would be examples of those.

Thank you all for the advice and info, especially Seele for the comprehensive post.
There's no indication of where the lenses were made, so am not completely sure of their origin (unless this rules out the 'British' lenses).
It looks easier, then, to find a body...
My question is : how would you rate such a system - is it worth it, how does it compare with my Nikon Fm2 + Nikon lens.
I only have a Nikkor 50mm at the moment, but as it happens am on the point of purchasing an 85mm. - am deciding which to go for - so it may or may not make sense to have the two systems. Bearing in mind also that I have almost exclusively been using a Mamiya RZ for the past couple of years but have recently returned to appreciating and using the Nikon, but don't feel the need to go too much overboard with 35mm.
David, your answer surprised me. It not like you to be offhand or mistaken.

Praktica has its own mount. The other major user of the Exakta mount was Topcon.
df cardwell, you got it backwards. One of the great attractions of the Alpa SLR system, not to be confused with the current MF Alpas, is its extremely short register, which allows lenses from most other SLR systems to be used on Alpas.
The best list of registers I've found so far is here: http://www.a1.nl/phomepag/markerink/mounts.htm If there's a better one available, will someone please post a link to it?

On the whole, your life will be simpler if you invest in just one 35 mm SLR system. Which one doesn't matter much, as long as you don't settle on something that has unreliable bodies, few lenses, really hard-to-find support, and doesn't accept much in the way of wide angle lenses. ZI bayonet mount Icarex, for example.

To be completely accurate, mine's an FM2n aswell.

I'm wondering whether it's worth the increase expense of getting a 9-element lens. I'm not sure about this, as bokeh isn't generally a problem. Sorry, this is a bit of an aside, but isn't really as for me it's all part of the question of what to spend the money on.
I have a 85mm lens the AFD 1,4 version.
