[modeleng] Re: TIG welded copper boilers

Rich,

Let me apologise to you and the rest of the crew - you are right I had not 
appreciated that Alan's original comment referred to an all welded boiler.

I guess I was led astray by my experience with what must have been an 
earlier version where only the longitudinal barrel joint was welded.

I am reminded of my school reports "Must pay more attention"!

Regards,


Barrie
