Blake & Lamb with Cambridge NY pan

I've got a few 1 1/2 & 1 3/4 coil spring B&L traps with the Cambridge NY stamping, Can't seem to find any info on them. Anybody got a little history to share?

In or about 1969 Blake & Lamb moved from South Britain Ct. to Cambridge N.Y., and entered into a manufacturing agreement with Woodstream. Around 1978 the Cambridge stamping came in, and remained on the market till late 1980. The Cambridge Pans are harder to come by and bring a little more collector wise.

Interesting, thanks for the response.
