The Comp TA and Turbo were sourced from both Tano and M-a-t-s-u-s-h-i-t-a. The latter is best known for their Panasonic brand and they also employed the acute angle cut on the chain stays of some of their better models (see pic). Given that they are a known source for some Turbo, this would be seem to be the more likely source. However, the serial number would tell us if it is a M-a-t-s-u-s-h-i-t-a frame, without a doubt.
