Local deal, advice needed

[symphonic]

I stumbled upon a local ad for a few lenses:

revuenon 1:2.8 f=135mm
revuenon 1:2.8 f=35mm
revuenon 1:1.9 f=50mm
vivitar 1:2.8 f=90mm
asahi pentax 1:4/50

It's a part of a lot (with a camera, filters, bag and so on) which sells for ~280$. I'd like to make an offer for the takumar 50/1.4 and vivitar 90mm, what would be a fair price if the lenses are in nice condition?

Also, are these revuenons any good? I'm not very familiar with those. I don't even know in what mount these lenses are, the ad doesn't even says the camera brand, but I think I can read ***FLEX on the photo (it's low-res, hard to distinguish the letters).

The camera looks to be a Revueflex, and the lenses look like M42 mount, although one might be Pentax K mount. The lens you're interested in will be a flavour of Macro-Takumar if it's f/4 as opposed to f/1.4.

Value? Difficult to say really.

Thanks. You're right, I misread the part about the takumar 50mm.

Well the Macro Takumar sells for around $200.00 on its own, and I would assume the Vivitar has to be worth something not far off that, so it looks a good deal to me if everything is in good condition.

The only 50/4 that Pentax made AFAIK was the M42 Macro-Takumar 50/4 -- I recently bought one (beat up) for US$55. If the leftmost lens is the Vivitar, it strongly resembles the 90/2.8 macro I bought a couple years ago for US$3 (also beat up). In good condition, those macro lenses are indeed worth something like US$200 each. And they are both great lenses. GO FOR IT!!!

Thanks, guys. I sent an email to the seller, hopefully we'll meet to check the lenses and if they're in good condition I'll buy this.
