Posted on Monday, February 22, 2010 - 11:08 pm:        I'm in the midst of repairing a K1000 for a friend, and what I was hoping was just stray light seal foam (HA!) is in fact desilvering on the prism... I was wondering what kind of experiences people have had with swapping in prisms from other Pentax's like the ME/ ME Super or the older Spotmatics, to which the K1000's are so closely related. I have a parts-only ME super I could dig into for a spare, but wanted to hear what others had to say before digging it out only to find out it did not fit the specs...   Ethostech Tinkerer Username: Ethostech Post Number: 150 Registered: 07-2006 Rating: N/A Votes: 0 (Vote!)

There is no other Pentax model from which you could cannibalise a replacement. And if you occasion upon a junker K1000 it is just as likely you'll find the exact same desilvering. I am in Australia and we have a world-class optical lab in Tasmania to which I snd my K1000 prisms for resilvering. It costs around $35. Replacing the prism on a K1000 is a fairly straightforward job.
