Rafa,

Looks well built to me. Probably MK or Supra retracts. The engine, if pumped, is an RF-P though, rear exhaust version of the SF-P. The pipe looks short for that engine but I might be wrong. What's it propped with? Put an APC 12x10W on it. It should turn sub 12K.

A little masking of the canopy area, a sanding and re-painting will freshen up the yellowed white. Looks well covered too.
