Default Modifications to an old Aster

I purchased a French 232TC Aster that was cheap as it was overpainted in grey with a brush, had some parts missing that I can make but it has never been run. As this model has a small single fill smithies boiler where water top up is by a trackside hand pump I decided to put in working water side tanks, axle pump and hand pump as I needed to strip it right down.
The images attached shows what the loco looked like when I got it ( better in the photo than it really was) and then onto the axle pump and plumbing that I fitted. The axle pump eccentric is operated by a scotch yoke (thanks for the idea Bill I learn a lot from your loco build postings) with a ball bearing on the eccentric (another of Bill's ideas here). I made a new cross member to hold the axle pump that I purchased ready made and fitted the plumbing back to the cab where the water by pass valve is and boiler clack valve. The original dummy side tanks slip outside and over the new water tanks with the main one extending into the cab for easy filling.
It's a tight fit in the cab as you can see but everything fits in well and I use the pump handle with cutouts on the end to operate the by pass valve as I found fingers wouldn't fit.
Along the way i added more roof detail and made the distinctively French curved sided coal bunker extension that was not on the original model then repainted the model in the original Aster green. These loco's were generally all black but I like the SNCF green that Aster applied.
I now have a loco that runs for longer without stopping to pump up for water but I found the original small Meths tank means I still do have to top that up often, but that's OK by me.
Hope this gives others incentive to do the same to early Aster models with a single fill boiler

Thanks everyone for the encouragement and Zephra the paint was obtained by taking my Aster 141R, another French loco in green, down to my local automotive paint supply where he has a sort of light source spectrograph thingy (don't ask me how it works) that gives him the paint "recipe" to mix it and then maybe adjust colour from there. He can supply me paint in half litre tins or in a spray can and I have used both. This service isn't common here in Australia but the equipment to analyse colour and to put into spray cans I believe is American supplied so someone will have this service where you are.
The paint is automotive acrylic and needs to be low temp baked (ask paint supply man) for use on boilers but on coaches and other non heat models it's good applied without baking. If airbrushing it needs to be well mixed and thinned down quite a bit for my little airbrush, about 2/3 thinners (often more) to 1/3 paint. Using his pre mixed spray cans it applies very well and this is what I generally use especially for the bigger surfaces on say a carriage.
This paint man is now used to me bringing in loco's and rollingstock for a paint match and asks me about my hobby all the time and fascinated by the steam loco's.

Hello der Peter, I haven't seen one of those loco's but it looks like you can do a conversion like I did with working side tanks. The axle pump and the hand pump I purchased ready made from an ebay site called Microcosm from China that are reasonably priced and work well.
One thing I have found is that even though I have two side tanks there is not much water in them so while I am topping up the fuel (with feed closed of course!) I put in water as well. Unlike a big water tank in a tender it needs topping up but as I have to do fuel as well it's no problem and I have had this loco in steam for nearly an hour once I get used it.
Also I put in two baffles to each water tank stop water sloshing back and forth as that can be a problem where water spill could wet the fuel wicks.
