BRDM Driver Posted November 9, 2012 Share Posted November 9, 2012 Periscope on the left removed from Abbot. Just a bit of light surface corrosion! :wow: Putting the one on the right back in once I get it treated and painted. All three were like that. Almost 1/3rd completely reduced to powder.

ChasSomT. Posted November 9, 2012 Share Posted November 9, 2012 That's why the original owners only fitted them when they were actually using the vehicles! 'Inter-metal corrosion' - Electrolitic or some such scientific term, reaction between the Aluminium periscope body and the steel of the turret. I clean them up, apply 3 or more layers of paint, allow to dry thoroughly, coat the 'joint faces' liberally with PURE silicone grease (Anything petroleum based, Vaseline, etc. will 'eat into' the rubber gaskets I hope you kept!) to keep water and air out, and refit. :cheesy: Purely by coincidence, I have a few periscopes available, at £55 for a set of 3. Obviously used condition. PM if interested 'Chas.' Quote Link to comment Share on other sites More sharing options...
