John did a few Senior CO2 conversions, of which I have one, and he did a Service PCP conversion which I also have. I have a very rudimentary drawing of the Service PCP conversion, which in no way could be called a blueprint, but the principles of the conversion are shown. I have no drawings of the Senior CO2 conversion.
John did CO2 conversions on a few different rifles, most of which I believe went to the states.

If the Holts LP53 CO2 conversion is by John, it's unusual in having the conversion drawings.
