What to do...

Hello, Bani.  I hope you had a good Christmas.  What you propose doing is not the strangest idea I've ever heard.  But why not try searching for a correct boiler for a while and, if unable to locate one, then proceed with your Prussian job?  It looks like it would be an adorable loco either way.

I don't think I'd worry about horrifying experienced tinplaters. That's all subjective.

Collectors of originals tend to view restoration/repaint from the perspective of destroying history. However, there are some items that are either of so little value, either monetary or historic, or are so far gone, that restoration, or personalization only improves the item. With your little locomotive, have to be the judge of that.

One way to view it is whether finding parts in suitable condition, time, effort, and cost justify it, or whether for the same level of effort, an original in working condition can be found.

You have to be happy in the end, and that's all that really matters. Enjoy.

Do what makes you personally happy! If this locomotive was mine, I would build a boiler, firebox and tender to my liking.

Welcome to tinplate trains!  I think you have received some good advice already.  If an item is in good original condition, most people would probably avoid any modifications.  However, if it isn't in good condition, or even an incomplete common item, I feel free to modify them without any guilt or reservation.  Since the loco in the picture is missing some parts and the remainder isn't in pristine condition, it wouldn't bother me to rebuild it into a custom locomotive.  And remember, they are your trains to do with as you please.

As a side note, I notice that your loco is a windup train... are all of your trains windup, or are some electric?  As a clockwork train enthusiast, that spring caught my eye... 

I would like to see the result of your project, whether you decide to restore it or customize it.  Of course, I would enjoy seeing pictures of the rest of your trains, too... especially if they are clockwork!

i did a quick search for "Hornby 50153" and got a number of hits...

it was a sharp looking locomotive, but doesn't seem to be that rare.  so whether you go for the original look or decide on another direction, more important that what is left could be revived vs. any unfounded pressure to restore it to an exact original design.

good luck... gary

Thanks everyone, I see the general consensus is to perhaps search around for replacement parts and if unsuccessful, go ahead with the conversion. Looks like it'll be up and running soon in some new colours!

James, indeed both my current possessions (and those I hope to purchase) are all clockworks! The only other loco is another Hornby, pictures of which will be up as soon as the restoration is done.

Sorry for the late (and short) reply, work has been really busy but it's funding the layout!

Bani

We'll definitely look forward to seeing photos of both your projects, whichever way you decide to go on this one!

I'll second that sentiment... Plus, I'm very glad to have another clockwork enthusiast on the forum!
