Wahey!! We have a winner! Correct guess ducv2. Conclusive proof - if it was needed - that all the biggest bike anoraks live in the North East!
And for the less knowledgeable of you (less sad even??) here's a full photo of the bike in question. Pushrod engine, kick-start, and twin-cylinder brother to the original 4cyl MV 750s.
Now ducv2, all that remains is that you e-mail me your best (biggest!) bike pic and I'll turn it into a poster for you. Bear in mind that the quality of the finished item depends largely upon the quality of the original image. Get in touch, and we'll sort out the details. Here's my e-mail address:
