No. 4 Mk 1/2 and 1/3

[Lance]

Surprisingly over the years I have encountered over 20 LB Mk 1/2's and at least 200+ LB Mk 1/3's. The LB Mk 1/2 is definitely rare but so are '41 BSA and Faz converted Mk 1/2's with Maltby being a little more common, but not much. I currently have 1 LB 1/2 and 2 LB 1/3's.
