Time for something a little different from me. I have invested in a little restoration project of a Tyers Absolute Block Instrument as used by the North Staffordshire Railway, this being very similar if not the same as one of the pair found in Leek signal box as to be found one day on Yorkies developing diorama/layout. I say restoration as it’s not quite complete. At first I thought I had a broken top half, and missing some mid sections and the front panel with the glass in it. But after having it about a day, I happened to put the lid down and it dawned on me by the fixture in the side that it had once had a lock in it…. Just like the bottom half of the rest of it.. turned out my “top” was actually a second bottom.. however the top panel is the same as the bottom so it may be a stalled renovation project by someone else to reuse the base as a new top.??? Well that’s my plan, and here will be some details of how it’s being done as we progress. But before that, here is a little more of the instrument.. opening the door we have the switch gear for sending the communications to the next box. It needs a great clean up, but nothing time and patience can’t do - and it’s all there! Here is the other half, these are the contacts which will work through a number of red relays behind the display panel. Also present inside were two service stickers. These date the last service in 1963 and also the resistance of each of the relay coils. it’s even stamped inside with NSR but the number 1925. We don’t know if this is the item Number or a build year… the latter would be odd as the NSR was absorbed in to the LMS in 1923! before we start the restoration, here is what it should look like, complete with its block bell box.
