Hi guys This liner has got me scratching my head. I know the companies involved in making liners leased out the liner presses from the US government and these often would have other makers marks on them. This is why we see Westinghouse logos with CAPAC logos, MSA marks in CAPAC/Westinghouse liners and Firestone would put there F logo over another makers logo. The liner in question has the CAPAC mold in mark that was seen on the production run between 1951 and 1954 ( I have never seen an example of this period logo mark on a P55 liner until now and I would love to see another example if anyone has one ) The numbers usually indicated the year of tooling not the manufacture year. On this liner though it has two lots of numbers 61 at the top and 53 on the bottom but on the examples I own and have seen elsewhere the number is 51 not 61. The CMC logo is situated below the CAPAC logo but on examples I have seen the 61 year is below the CMC logo but on this one it is situated in the CAPAC logo above it.
My question would be, was this an un-pressed liner left over from the early 50s then pressed in 61 under the CMC logo or has it been pressed with a press from this period and the numbers modified at time of pressing? Sorry for waffling on but this has me stumped.
