Oh course it's that one thought it looked familiar, what's the material state of it like then,
240 mph would be an achievement, some one may do a jet engine conversion in the future so it's worth keeping the speedo for that!
I would love to change my speedo to read mph as mine in k but someone drew on some shoddy mph units up to 70 on my speedo, anything above 70 Is a. An achievement and b. an optimistic guess
