Carl - I have to admit to being really intrigued as to what some of
Mr Herrick's conversions look like. Did you manage to find any of the photos you were referring to?
I love the whole concept of conversion, and repurposing. That's why this beautiful rifle kindly shared by
clank has got me thinking about how or where i would even begin to build something like this.
If you don't know
Theo Hegman's work - a man whose rifles are all 'ONE-OFF' unique builds - then check out the link below. His are all quite extraordinary:

He also very kindly includes expanded details on each of the examples here (the expanded links are usually 'blue text')....
....with outline design drawings to show you how they work. I really like his work which is mostly pcp, although he does include one called The CHIPMUNK which is one of the few 'springers' he has shown here. Two springs... innovative design... just gorgeous:
