Well, finally started my first 35mm film - got 8 seconds for a really great deal, so figured that will be a good one to practice on! Machine is still at the office, so my screen is currently the concrete wall above the coffee station in the fileroom - but, everything worked! When I bought it, the soundhead was missing the right side cover - I found a replacement on ebay, so sandblasted and re-painted both covers to match (they were pretty chipped up) - now all that's left is to get a new knob...

That sounds great! I wish I had the space for something like this :-)
