I'm getting a quote on having an airbox for my 51 Plunger 67-4594 (Air cleaner and battery carrier combined, plus the element cradle) professionally made using a complete one that I have as the template. Knowing how rare these critters are, if anyone else is interested in purchasing one, i'd be happy to hear from you. Serious expressions of interest with no obligation to purchase.
I figure 1 airbox will cost a pretty penny, but if I can get a second quote for an order of several, I'd hope the price will reduce and all benefit.
Yes risk for all of us. But finding then buying these things in any condition is filled with a far greater risk. I will post pix of the new airbox if the initial price does not prevent me going ahead.
Next negative, for those who know the sky has fallen in, I am in Western Australia, happily near the most remote capital city in the world. So postage won't be free !!!
