Thanks pak, I have a few 46 models. My first rifle (which I still have) was a 46B(b), The 144LSA was a hard one for me to find and I am still missing a 144US to complete the series. I have a144, 144LS, now 144LSA, 144LSB (early - no serial number) and a 144LSB with a serial number. I bought the 2nd LSB in 1973 or 74. I also have a 352KC I bought in 1972.
