Identify This
 

I have a Driver's vision Block ,but not sure if this is carrier related?
Has TL 3195 part no. and maker is Mel and co. 1955 ?? What's this from?

Vickers light tank. But the same or very similar style as the Dingo.

Were they common between types? This would make sense but remembering they were a British design I find this common sense approach unlikely.......

Without checking the number, it looks like the block for a Daimler Dingo. The prefix, TL (Tanks, Light) may indicate that this block originates from the Vickers Light Tank MkIV, but the postwar date would still be OK for a Dingo as parts were still being made into the mid Fifties.

Vision Block
 

The Dingo slot to take a vision block would appear to be 8 1/4 inches wide. This block measures 8 3/8 overall width. The tabs on the sides measure 1/2 wide , as does the slot from a Dingo..... confused?

Hi Andrew,
Just checked the Dingo block number and it is TL935A, being made in 1955 and basically a WW2 design is interesting and may be a clue.
